High Spin States in the Odd-Odd Nucleus exp 108 IN

摘要

Levels in exp 108 In were studied using the exp 98 Mo( exp 14 N,4n gamma ) exp 108 In reaction at 65 MeV. The experiments included gamma -ray yields as a function of bombardment energy, gamma - gamma coincidence measurements, gamma -ray angular distributions, gamma -ray linear polarization and conversion electron measurements. gamma -ray intensities were also extracted from the exp 108 Cd( exp 3 He,p2n gamma ) exp 108 In reaction at 40 MeV. The exp 108 In level scheme exhibits a simple structure including only 13 levels. The main feature consists of delta I = 1 transitions based on the 1119.3 keV level (7 exp - ) and the 2514.3 keV level (9 exp - ). However no delta I = 2 transition was observed. The lower band is interpreted in the frame of the rotor + two quasi-particle model. (Atomindex citation 12:583754)
