Abstract

The isotopes 130, 132, 134, 136Ce are investigated by means of the reactions 118, 120, 122, 124Sn(16O, 4n) at bombarding energies between 68 and 76 MeV. From lifetime measurements a reduction of the collective behaviour is observed with increasing neutron number. Yrast cascades of rotational structure are identified up to angular momenta I = 16+ orI = 18+ in 130, 132, 134Ce. These cascades show a strong “back-bending” effect. In 136Ce no such simple yrast cascade could be found
