G. Canchel et al., A new 350 MS isomer in La-125 and low energy intrinsic states in A=133, 131, 129, 127, 125 La isotopes, ACT PHY P B, 30(5), 1999, pp. 1239-1244
By means of the HIGISOL technique, the A = 125 mass chain was studied via b
eta(+)/EC decay of Ce-125 and a new (350(40)(+60)) ms isomer was definitely
assigned to La-125 based on conversion electron measurements.
