Quadrupole deformed and octupole collective bands in 228Ra
Abstract
Spins and parities for collective states in 228Ra have been determined from conversion electron measurements with a mini-orange β spectrometer. The fast-timing βγγ(t) method has been used to measure lifetimes of T12 = 550(20) ps and 181 (3) ps for the 21+ and 41+ aembers of the K = 0+ band, and T12 ⩽ 7 ps and ⩽6 ps for the 11− and 31− members of the K = 0− band, respectively The quadrupole moments, Q0 deduced from the B (E2; 21+ → 01+) and B …
