Abstract

The study of deformed structures in the light 4n self-conjugate nuclei is carried out using (n_xn_yn_z) single-particle representation and the same effective interaction for all nuclei considered. In this work, we treat the whole system of A nucleons, without any reference to a core. The rotational energy spectrum has been calculated by projecting out good angular momentum states from the axially symmetric deformed Hartree-Fock states. In ⁸Be and ²⁰Ne the low-lying states can be well described using a simple deformed state but this is no longer true in ²⁸Si. It is shown that the ¹²C nucleus exhibits the same structure as observed in ¹⁶O. In this nucleus the low-lying states are mixtures of 0p-0h, 2p-2h and 4p-4h deformed states. The computed electromagnetic transition rates are compared to the experimental ones. A comparison with the SU₃ scheme is made.

Four-nucleon pickup reaction on 12 ≤ A ≤ 94 nuclei
1984, Nuclear Physics, Section A
The differential cross sections for the (d, ⁶Li) reaction on targets of ¹²C, ¹⁶O, ²⁴Mg, ⁴⁰Ca, ⁵⁸Ni and ⁹⁴Mo have been measured at E_d = 54.2 MeV. The measured angular distributions have been analyzed by finite-range DWBA calculations, and spectroscopic factors for an α-cluster transfer have been extracted. In the DWBA analysis using an optical model with a phenomenological Woods-Saxon potential, the spin-orbit part of the deuteron optical potential played a significant role in reproducing the measured angular distributions but the spin-orbit part of the ⁶Li optical potential had a minor effect. Relative spectroscopic factors extracted from the present data were compared with theoretical predictions together with the results from the (p, pα) reaction. The relative spectroscopic factors for 1p-shell nuclei were in quantitative agreement with theoretical predictions. However, there were certain discrepancies between the spectroscopic factors extracted from the (d, ⁶Li) reaction and those from the (p, pα) reaction, and the discrepancies increased with target mass number.

The interplay of cluster structures in light nuclei: The model and the application to 7Li
1978, Nuclear Physics, Section A
The structure of light nuclei is treated as a superposition of different cluster structures. The wave function of a nucleus contains the components describing two-cluster structures constructed out of 1p shell and/or 1s shell clusters. The model is used to study the low-lying energy levels of the nucleus ⁷Li, whose structure is treated as a superposition of the cluster structures $(^{4} He +^{3} H)$ and $(^{6} Li + n)$ .
The space of the wave functions is spanned by antisymmetrized products of shell-model wave functions describing separated clusters. The separation S of the two shell-model potentials is taken as the generator coordinate. The projection of the generator coordinate wave function onto the eigenspace of angular momentum and parity operators is performed by an algebraic method based on an algorithm which expresses the effect of the rotation of the wave function in terms of the rotation of the generator coordinate S. This method enables one to express the matrix elements in the projected basis as a finite combination of matrix elements in the unprojected basis.
The application of the model to the nucleus ⁷Li has shown the feasibility of the calculation with 1p shell clusters. The Volkov potentials were used in the calculations. The minimal energy of ⁷Li in the state described by the model function with fixed separation of the clusters ⁴He and ³He is lowered by 1.64 MeV by solving the Hill-Wheeler equation for the cluster structure $(^{4} He +^{3} H)$ . The coupling of both cluster structures lowers the energy in addition by 0.32 MeV. The influence of the coupling on the shape of the nucleus is a follows: In the single cluster structure $(^{4} He +^{3} H)$ the optimal separation of the clusters in the ground state is 3.5 fm and it is 0.5 fm larger than that in the first excited state $52^{−}$ . However, when both cluster structures are considered simultaneously, the optimal separation between the clusters ⁴He and ³He and the separation between the clusters ⁶Li and n in the ground state are equal to the corresponding separations in the excited state.

Projected spectra of light nuclei with Skyrme interactions
1977, Nuclear Physics, Section A
In the framework of the projected Hartree-Fock theory, rotational bands in light nuclei are described using Skyrme interactions. Comparison with traditional interactions and discussion of the Skyrme parametrization are made. A Skyrme interaction is derived which allows a better description of rotational bands and α-type excited bands. This is achieved through a modification of the parameter of the velocity dependent part of the force.
