Abstract
Microscopic calculations of the (p, p′) cross sections of the low-lying 2 + and 3 − collective levels in the tin isotopes are presented. A nucleon-nucleon force and RPA wave functions are used. The proton and neutron transition densities are renormalized in such a way that calculated values of both (p, p′) cross sections and electromagnetic reduced matrix elements B(E j) are in good agreement with the experimental ones. Then the proton and neutron transition densities “truly” existing in the nucleus are compared. A comparison with the effectivecharge method is also given.
