E2 contributions to backward (e,e') cross sections

in heavy deformed nuclii

M. Dingfelder, R. Nojarov, Amand Faessler

It is shown that E2 transitions to the rotational band of low lying M1 excitations in heavy deformed nuclii contribute to the M1 (e,e') cross section at backward angles even at low incident energies of 50 MeV. The agreement with experiment is improved considerably, especially for intermediate transferred momenta, after taking the E2 contributions into account.
