Abstract

The β+/EC decay of 126La produced by the 94Mo(36Ar, 3pn) reaction has been studied using the on-line isotope separator connected to an AVF cyclotron. Gamma-ray singles, γ-γ angular correlation and internal conversion electron measurements were carried out. From analysis of these data, 33 new levels in 126Ba were found and the decay scheme containing 137 γ-rays and 50 excited states was constructed. The probable spin and parity of the two β-decaying states in 126La were found to be 4±, 5± for the high-spin isomer with a half-life of 54(2)s and 0-, 1±, 2- for the low-spin isomer with a half-life shorter than 50s.
