Abstract
Mean lifetimes of the high spin states in the yrast band of 126Ba were measured by
using the Doppler shift attenuation method in connection with the reaction 116Sn (16O,
2p4n)126Ba at a beam energy of 73 MeV. The corresponding normalized B(E2) values are
obviously reduced in the vicinity of the backbending. The results are compared with the
theoretical predictions based on a realistic nucleon-nucleon interaction.
