摘要: High spin states of 157Er have been populated using the 114Cd+48Ca reaction at a 48Ca bombarding energy 200 MeV. Gamma rays were detected in an array (TESSA2) six escape-suppressed Ge spectrometers and 50-element BGO multiplicity summed detector. Decay scheme angular correlation data obtained from gamma - coincidence The yrast band has identified up to 65/2+ two negative parity sidebands (one previously unobserved) 69/2- 63/2-. An additional sideband transitions was also observed. structures are interpreted terms quasiparticles framework cranked shell model.
