Abstract

The equations-of-motion formalism is used to extend the RPA (random-phase approximation) to the negative parity excitations of open-shell nuclei. Thus the open-shell RPA extends the simple microscopic description of collective vibrations to non-simple nuclei and renders a whole new range of nuclei accessible to microscopic theoretical investigation. As a simple example, the model is applied to describe the negative parity excitations of ¹²C based on an uncorrelated ground state taken from a shell-model calculation within the $1 p_{32} and 1 p_{12}$ sub-shells. Comparison is made with the (much less realistic) standard RPA for which the uncorrelated ground state is taken to be the closed $1 p_{32}$ sub-shell.

The coupled-rotor-vibrator model
1989, Nuclear Physics, Section A
Some recent advances in the theory of dynamical groups are used to extend and put the CRV model on a more rigorous microscopic foundation. We show that vector-coherent-state theory provides exact rotor expansions of Elliott's su(3) operators as well as boson expansions of the giant-resonance excitation operators. The rotor expansion leads to simple analytic expressions for su(3) matrix elements that are exact in many situations and, in general, accurate to high order in a small parameter L/2λ + μ, for λ ⩾ μ, and in L/λ + 2μ, for λ < μ. These expressions provide useful and accurate hand-calculator alternatives to implementation of the exact algorithms available for the computation of su(3) matrix elements in an so(3) basis. They also provide valuable insights into the physical content of the su(3) model in rotor-model terms. Another recent development shows that the rigid-rotor and SU(3) models can survive the effects of strong representation mixing due, for example, to spin-orbit and other interactions, albeit in a “softened form”. We incorporate this development into the CRV model and show that, as a consequence, nuclear rotational bands and their vibrational excitations have natural microscopic origins in valence-shell su(3) representations with strong renormalization and “softening” due to the effects of coupling to higher shells and representation mixing. Some implications of the results for the microscopic interpretation of rotational spectra in heavy nuclei are discussed.
Small amplitude vibrations in symmetry-projected quasi-particle mean fields
1989, Annals of Physics
The solution of the Hartree-Fock-Bogoliubov problem with symmetry-projection before the variation as it has been formulated within the VAMPIR approach leads to symmetry-dependent and, in general, essentially complex mean fields are studied. Tamm-Dancoff as well as random-phase-like equations are derived and discussed. It is shown that for the case of time reversal invariant and axially symmetric Hartree-Fock-Bogoliubov transformations the resulting random-phase equations can be brought into a form involving only real matrices. Advantages and shortcomings with respect to other approaches are investigated.
A modified RPA for open-shell nuclei
1988, Nuclear Physics, Section A
A modified RPA suitable for open-shell nuclei is constructed using the Green function method. Unlike the standard RPA, this modification makes allowance for the spread of bound single-particle and single-hole states over more complex configurations which is done due to a more realistic approximation of single-particle Green functions. The calculations of the nucleon-nucleus S-matrix and of the probability amplitudes for the single-particle transitions of the nucleus from the ground state into scattering states are examined. For the separable effective forces these quantities are expressed in closed form.
Partial photonucleon cross sections and the 24Mg giant dipole resonance
1988, Nuclear Physics, Section A
The (γ, n_i) cross sections in the region of the giant dipole resonance (GDR) of the self-conjugate ²⁴Mg nucleus have been obtained on the basis of the experimental (γ, p_i) cross sections (i specifies states of the final nucleus) and the isospin symmetry of photonucleon decays. In the (γ, n_i), (γ, p_i) cross sections, the total photonucleon cross sections, and the photoabsorption cross sections, we have identified the components due to semidirect GDR decay using the ratios of the semidirect decay widths resulting from the R-matrix theory. In the integrated photoabsorption, photoproton, and photoneutron cross sections the probability of semidirect decays was found to be 57–67%, 45–60%, and 80–90%, respectively.
The semidirect decays dominate in the low-energy (<22 MeV) group of the GDR containing the transitions $1 d 2 s → 1 f 2 p and 1 p 12 → 1 d 2 s$ and the statistical decays dominate in the high-energy (> 22 MeV) group of the transitions $1 p_{32} → 1 d 2 s$ .
12C(p, n)12N and 16O(p, n)16F reactions at E<inf>p</inf> = 35 and 40 MeV: Reliability of the information obtained from DWBA analysis of low-energy (p, n) data
1987, Nuclear Physics, Section A
A high-resolution study of the ¹²C(p, n)¹²N and ¹⁶O(p, n)¹⁶F reactions was made at E_p = 35 and 40 MeV. The low-lying states in ¹²N(1⁺, 2⁺ and 2⁻) and in ¹⁶F(0⁻, 1⁻, 2⁻ and 3⁻) were clearly resolved, and their angular distributions were measured. Extensive DWBA analysis was made and compared with the data. The calculated angular distribution shapes are found to be in agreement with the data and insensitive to the choice of the parameters involved. On the other hand, the magnitudes of the DWBA cross sections depend strongly on the bound state parameters in the case of a transition from a tightly bound state to a loosley bound state. In the other cases the overall uncertainty of the DWBA cross section magnitudes was estimated to be about ±30%. Within this uncertainty the experimental cross sections for the ¹²C(p, n) reaction were explained by the calculation, but those for the ¹⁶O(p, n) reaction were not: the observed strengths were about a half of the calculated values. Since these results agree with those at intermediate energies, the origin of the discrepancy is considered to be in the structure of the mass 16 nuclei rather than in reaction dynamics. In general, the present results compare well with those at intermediate energies, indicating that the structure information extracted from low-energy, high-resolution (p, n) data is basically sound if careful analysis of the data is made.
The coupling of valence shell and particle-hole degrees of freedom in a partial random phase approximation
1987, Nuclear Physics, Section A
It is well known that the random phase approximation breaks down in the absence of a substantial energy gap between occupied and unoccupied single-particle states. Particle-hole excitations are then inevitably accompanied by substantial rearrangements of the particles in the neighbourhood of the Fermi surface. To accommodate this situation, a partial RPA is introduced which corresponds to replacing only the particle-hole degrees of freedom by bosons but leaving the valence space degrees of freedom intact. The PRPA is therefore a mapping of the many-fermion dynamics into the dynamics of a coupled boson-valence space. In application of the PRPA, algebraic methods, of either a fermionic or Lie algebra type, can be introduced, if desired, to facilitate the treatment of the valence space degrees of freedom. Results of applications are presented in which the valence space particles are treated in the rotational and SU(3) models, and are coupled strongly to giant dipole and quadrupole resonances.
