Abstract

Some properties of the low-lying levels in the odd-nucleus La140 as populated by the beta decay of Ba140 have been studied by beta-gamma and gamma-gamma directional correlation experiments. The multipole orders and the E2/M1 mixing ratios of the promiment gamma-rays have thus been measured. On the basis of these measurements the following spin assignments to the La140 levels have been made: 30 keV (2), 162 keV (2) , 466 keV (1) and 566 keV (1). The 162 keV gamma ray is predominantly of E2 character with the reduced transition probability at least 90 times that of a single-particle transition.
