T1 - Yrast cascades in even mass Ce isotopes JF - Nuclear physics A N2 - The isotopes ¹³⁰,¹³²,¹³⁴,¹³⁶ Ce are investigated by means of the reactions ¹¹⁸,¹²⁰,¹²²,¹²⁴ Sn(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⁺ or I=18⁺ in ¹³⁰,¹³²,¹³⁴ Ce. These cascades show a strong “back-bending” effect. In ¹³⁶ Ce no such simple yrast cascade could be found. Y1 - 1974 SN - 0375-9474 U6 - http://dx.doi.org/10.1016/0375-9474(74)90361-3 VL - 225 IS - 1 SP - 1 EP - 15 PB - Elsevier CY - Amsterdam ER -
