Abstract
Transitions between the electronic states and their linewidths of Tb and Pr doped for La in the superconductors LaAl2, LaAg, LaSn3, and LaPb3 have been measured applying inelastic neutron scattering. The linewidths can be correlated with relaxation processes to the conduction electrons, which at low temperatures and for increasing RE concentration are dominated by effects of the electrostatic and magnetic local environment. Selfinduced moments in the nonmagnetic groundstates of Tb are the reason for anomalies in the concentration dependence of the superconducting transition temperaturesKeywords
