Abstract

The gamma-ray decay of excitd states of the one-valence-proton nucleus 133Sb has been studied using cold-neutron induced fission of 235U and 241Pu targets during the EXILL campaign at the ILL reacor in Greonble. Lifetimes analysis, performed by fast-timing techniques with LaBr3(Ce) scintillators revealed a difference of almost two orders of magnitude in the B(M1) strength for transitions between positive parity medium-spin yrast states.
