Antisymmetrized distorted wave theory of inelastic nucleon scattering

摘要: Abstract Transition amplitudes for inelastic nucleon scattering from nuclei are developed using an antisymmetrized distorted wave approximation. Nuclear states specified by a microscopic model of nuclear structure. The transition operator includes central tensor and core polarization terms. A collective approximation is used to define the contribution. force has Yukawa form while chosen have modified shape. Inelastic proton first excited state 89 Y analysed incident energies 18.8, 24.5 61.2 MeV. In addition, analysis 61.4 MeV protons 5 − 90 Zr at 2.315 excitation reported. Good fits data obtained. Large effects due exchange matrix elements noted. Strong variations in results seen when interaction singlet triplet strengths varied. plays important role modifying contributions. For odd channel required our analysis, 10 % values. With more realistic form, this expected increase may be 30 %. lower energy require density dependence effective interaction. This complements such requirements recent spectroscopy studies. Also importance small-amplitude configuration mixing evident. contributions that represents summation terms necessary features analyses. particularly so reaction.
