摘要：

Excited states of Ce-142, populated in deep inelastic reactions of 82 Se projectiles bombarding La-139 target, have been studied up to medium spins using in-beam gamma spectroscopy techniques. Three new levels have been identified at 2625, 2995, 3834 keV, and assigned as 8+, 9((-)) and 11((-)), respectively. These now yrast states follow closely the level systematics of the even mass N = 84 isotones. Their structures have been discussed with the help of empirical shell model calculations.
