title: Decay scheme of 126La isomers.
abstract: The beta+/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, gamma-gamma 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 gamma-rays and 50 excited states was constructed. The probable spin and parity of the two beta-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 50 s.
