Abstract
The level scheme of the N = 79 nucleus Tb-144 was investigated via in beam gamma-ray spectroscopy using the Sn-112 (Cl-35,n2p), Sn-116(S-32, 3np) and Y-89(Ni-58,2np) reactions. States up to I similar to 20 and E (x) similar to 5 MeV were established above the 6(-) beta(+) decaying isomer. Two new isomers with half-life of 0.67(6) mu s and 2.8(3) mu s were identified. The level scheme of Tb-144 is interpreted in the fra mework of the spherical shell model with a few valence nucleons outsid e the Gd-146 core.
