Nuclear structure of 122Xe studied via high-statistics β+/EC-decay

The nuclear structure of 122 Xe has been investigated with measurements of the β + / EC decay of 122 Cs with the 8 π γ -ray spectrometer at the TRIUMF-ISAC facility. The data collected have enabled the determination of relative B(E2) values of some low-energy transitions, and the in-band transitions of the excited 0 + bands have been observed. As a result, the 2 + rotational band members for the 0 + 2 and 0 + 3 states have been firmly identified.
