Abstract
Using an on-line mass separator, the α-particle decays of155Lu and157Lu were investigated. A new α-emitting level in157Lu was identified [T1/2=5.7(5) s,E β=4924(20) keV]. In addition, a half-life of 140(20) ms was measured for the recently discovered second, low-lying, α-decaying level [E β=5579 (5)keV] in155Lu.
