Abstract

The photoproduction of 0–150-MeV charged pions from light nuclei is studied from a distorted wave impulse approximation (DWIA) approach. The final nuclear states are restricted to a finite set of isospin analogs of excited states of the target nucleus. The final state interactions of the pion with the residual nucleus are incorporated via optical potentials. The elementary photoproduction operator used is that of Blomqvist and Laget which is derived in a general reference frame. To gain insight into the predictive power of this DWIA approach, total and differential cross sections for π^± production from ⁶Li, ⁷Li, ¹⁰B, ¹²C, and ¹⁴N are calculated and compared with available data. It is found that, with a few exceptions, reasonable agreement is obtained between theory and experiment as long as the nuclear wave functions are constrained to fit other electromagnetic and weak processes and the optical potentials are constrained to fit pion-nucleus elastic scattering data. We conclude that, at this stage, using the Blomqvist-Laget operator in a DWIA calculation adequately describes the dynamics of charged pion photoproduction from complex nuclei. We illustrate how this reaction can be used to obtain information on the short range nature of the pion wave function and on nuclear wave functions. Shortcomings of and improvements on this calculation are also suggested.

A relativistic description of the quasifree radiative pion-capture reaction on nuclei
1995, Nuclear Physics, Section A
We present a relativistic model for the reaction A(π⁺,γp) A − 1. This is an extension of our recent model for negative-pion photoproduction. The interaction of the pion with the target nucleon is comprised of the set of Born terms arising from the pseudovector form of the pion-nucleon interaction lagrangian, as well as s- and u-channel diagrams involving the propagation of the Δ(1232). The bound and continuum nucleons are described by solutions of the Dirac equation with appropriate scalar and vector potentials, while the pion wave function is a solution of the Klein-Gordon equation containing a pion-nucleus optical potential. Calculations of the triple differential cross section $d^{3} σ dω_{p} dω_{γ} d Eγ$ as well as the polarization of the final proton are presented for the kinematics of TRIUMF experiment 550. Under appropriate kinematic conditions the contribution of the Δ(1232) is found to be dominant in this reaction. The results are sensitive to the choice of pion-nucleus optical potential but are not very sensitive to the nucleon interactions with the nucleus. We obtain qualitative agreement with data from TRIUMF experiment 550.
Distribution of spin-isospin strengths in 12B and 13B
1994, Nuclear Physics, Section A
The differential cross sections of the reactions ^12,13C(γ, π⁺)^12,13B were measured using tagged photons at the mean energy E_γ = 191 MeV at five angles 35° ⩽ θ_π ⩽ 145° corresponding to the momentum transfer to the nucleus 0.5 ⩽ q ⩽ 1.5 fm⁻¹. The major transition strengths leading to various excited states in ^12,13B, in both cases, are concentrated within a resonance centered at about 7 MeV excitation energy in ^12,13B (about 22 MeV in ^12,13C) with a full width at half maximum (FWHM) of about 12 MeV, reminiscent of the well-known electric-dipole gian resonances. The two reactions are compared in the context of the weak-coupling model.
A relativistic model for quasifree negative-pion photoproduction on nuclei
1994, Nuclear Physics, Section A
A relativistic model for the negative-pion photoproduction reaction (γ,π⁻p) on a nucleus is discussed. The interaction of the photon with the target nucleon is comprised of the set of Born terms, arising from the pseudovector form of the pion-nucleon interaction lagrangian, as well as s- and u-channel diagrams involving delta propagation. The amplitude is calculated in a relativistic distorted wave framework. Both the bound- and continuum-state nucleons are described by solutions of the Dirac equation with appropriate vector and scalar potentials. The pion wave function is a solution of the Klein-Gordon equation, and the interaction of the pion with the residual nucleus is taken into account via an optical potential. The calculations are done in coordinate space and require the solution of eight-dimensional space-time integrals, which are simplified by making a local approximation to the propagators, allowing the integration at one vertex to be done trivially. As expected we find the contribution of the delta to be important in the resonance region, but in general the delta contribution is smaller than the contribution of the Born terms. The effects of changes in the binding and interaction potentials on the cross section and spin observables are studied and found to be small. We compare the results of the model with the few cross-section data sets available and find qualitative agreement in most cases.
Delta-hole approach to (γ, π-p) reaction at resonance energy

Spin-isospin excitation in 12C(γ, π+)12B* using tagged photons
1990, Nuclear Physics, Section A
The energy spectra of positive pions from the reaction ¹²C(γ, π⁺)¹²B^∗ were measured at five angles, using quasi-monochromatic, tagged photons in the energy range from 176 to 182 MeV. Strong transitions to the isovector nuclear states in ¹²B at 0–1, 4.5, and 7.5 MeV were observed. The differential cross sections to these states have been obtained for the momentum transfers 0.5 < q < 1.2 fm⁻¹. DWIA calculations have been carried out in momentum space for each observed state or group of states. Comparisons are made between the present data, previous data from bremsstrahlung experiments, and various DWIA calculations.
E0 suppression in pion photoproduction on 13C
1990, Physics Letters B
The photoproduction process ¹³C(γ, π⁻)¹³N is reinvestigated in a nonlocal DWIA framework which includes selected configurations beyond the 1p-shell. We find a strong sensitivity of the E0 contribution of the pion production cross section to contributions from higher shells. A small amount of (2p, 1p⁻¹) and (1p, 2p⁻¹) admixtures leads to a significant suppression of the E0 part and can provide agreement with experimental data.
