LIFETIME MEASUREMENTS OF EXCITED STATES IN 76Kr

Abstract: Lifetimes of excited states in the even parity yrast, γ-type vibrational and nega-tive parity Band in 76Kr were measured by the Doppler shift attenuation method. Thelifetimes or composite feeding times of thirteen excited states in 76Kr were determined.The transitions in each of the three band are highly collective, and the transition in-tensity is the order of 100 single particle units or more.
