“…Systematics of the quasi-β and -γ bands in Ce isotopes. 142,144 Ce from [5,6], 146 Ce from the current work, 148 Ce from [7] and 150 Ce from [8] the corresponding experimental value of (4 3 → 2 1 1453.5 keV)/(4 3 → 4 1 1043.6 keV) was about 0.4, while (4 4 → 2 1 1543.8 keV)/(4 4 → 2 1 1134.0 keV) was about 2.1. The assignment of the 4 3 level as the quasi-γ state is consistent with the intensity ratio.…”

The β-decay of 146 La was studied using the on-line isotope separator KUR-ISOL. Gammagamma angular correlation measurements were performed with a 4-Ge detectors system. Spin assignments of three levels were made: 3 + for the 1576.5 keV level, 4 + for the 1627.1 keV level and 5 + for the 1810.2 keV level. The mixing ratios (E2/M1) were deduced to be δ183.2 = 0.25±0.08, δ638.9 = 0.33±0.05, δ959.0 = 1.19 +0.16 −0.14 , δ1015.9 = 5.4 +3.1 −1.5 and δ1318.1 = 6.5 +1.7 −1.1 . These were compared to the calculated values obtained in three cases involving different Majorana force parameter values. The band structure of 146 Ce is discussed based on the results of calculation using the IBM-2 theory.

“…Wolf et al [4] measured γ-γ angular correlations on rather strong cascades in 146 Ce generated through the β-decay of the low-spin isomer of 146 La. Studies of other even Ce isotopes (N = 88) have been carried out at several laboratories [5][6][7][8].…”

“…With the availability of isotope separators on-line (ISOL), it is feasible to investigate these nuclei precisely from the decay of their short-lived precursors. Recently, the studies of even Ce isotopes (Z= 58) were carried out at several laboratories [1][2][3][4][5][6][7][8]. The study of the nucleus ~46c,_ is of 58~t788 interest because it is located at the onset of deformation of the rare-earth region.…”

Abstract. The decay of 10.0 s high-spin isomer of 146La to levels of 146Ce has been studied using the on-line isotope separator KUR-ISOL. Gamma-ray singles, y-y coincidence and conversion-electron spectra have been measured. A level scheme containing 90 levels and 206 y-ray transitions has been constructed for 146Ce, populated in the decay of the high-spin isomer of 146La. Among these, 39 levels are reported for the first time. Spins and parities for some levels are proposed on the basis of y-decay mode, logft values and conversion-electron measurements. The band structure of the low-lying levels in 146Ce is discussed.
