Abstract

The decay of the 38.9 h isomer of Ba133 has been investigated. The energy of the d32 → s12 transition was determined by conversion electron measurements to 12.29±0.04 keV and the L subshell ratios of the same transition were found to be 100/9.6/3.1. The half-life of the 12.3 keV level was measured to 8.1±2.0 ns. The K conversion coefficient and the K/(L+M) ratio of the 276 keV h112d32 transition were measured with the result: αK(276) = 3.45±0.20 and K/(L+M) = 2.55 ± 0.10.

The pairing plus quadrupole force model seems to explain the experimental data quite well.
