The 88Sr(p, p′) 88Sr ∗ reaction at 20 MeV and antisymmetrized microscopic DWBA

The elastic and inelastic scattering of 20.2 MeV protons from 88Sr has been studied. Angular distributions for the elastic and 14 inelastic groups were measured. The inelastic scattering was compared to the collective model of distorted wave approximation for multipolarities ( l) assignment and determination of strength parameter β l . The inelastic scattering to some states was also compared to coupled channel calculations and distorted wave calculations including antisymmetrization and using a microscopic wave function. In the latter case, reasonable agreement is obtained for the lowest 3 − state but the inaccuracy of the 2 + and 4 + states wave functions is reflected in the calculation of the differential cross sections. The effect of antisymmetrization is shown on a simple model.

Use of Antisymmetrized Wave Function for Deuteron Stripping Reaction

The general S matrix of nuclear reaction is derived by the method of second quantization in order to take account of antisymmetrization of the total system. As an example of the general theory, a deuteron stripping reaction is treated. The amplitude obtained by this method is compared with those obtained by other theories in this reaction. The amplitude of this reaction is discussed for a special target which seems to demonstrate the effect of antisymmetrix zation most clearly. In the case of O/sup 17(d,p)O/sup 18/ the effect of antisymmetrization becomes comparable with the direct part. (auth)
