Abstract

The level scheme of ¹⁴⁷Tb has been extended up to 13.8 MeV excitation energy and spin I=67/2 using the ¹²⁰Sn(³¹P,4n) reaction. Evidence for a new octupole band built upon an excited multi-particle-hole state has been found. The high spin levels are interpreted in the framework of DIPM model and presents an evolution towards sizeable oblate shape at the highest spins.
