High spin states in 70Ge

Abstract

High spin states in 70Ge nucleus have been studied in two different experiments using heavy ion fusion evaporation reaction. The Gamma Detector Array, comprising of eight Compton-suppressed High Purity Ge detectors, was used in conjunction with a recoil mass spectrometer - the HIRA - in order to identify and measure the transitions of this weakly populated nucleus. The level scheme is extended up to an excitation energy of 13 MeV for spin-parity 21- with several newly observed transitions placed in it. A rotational like band is also observed in this nucleus for the first time.
