No Anomaly of the B(E2) Value Around the Backbend in 130Ce
Abstract： The lifetime measurements of the high-spin states in the yrast band of 130Ce have been performed by using the Doppler shift attenuation method in conjunction with the reaction 116Sn(16O,2n)130Ce at a projectile energy of 73MeV. The reduced transition probabilities B(E2) deduced from these measurements show a great reduction in the vicinity of the backbending region. The previously reported anomalously high B(E2) value was not observed in the present experiment. This result is in agreement with theoretical prediction based on a realistic nucleon-nucleon interaction.
