STATES IN CD-106 POPULATED BY HEAVY-ION (XN) REACTIONS INTERPRETED BY A 2-QUASIPARTICLE-PLUS-ROTOR MODEL

Levels in Cd106 were studied using (heavy-ion, xn) reactions. The experiments included -ray yields as a function of bombarding energy, -ray angular distributions, -ray linear polarizations, and - coincidence measurements. The decay scheme, which includes 85 -ray transitions, is similar to those reported for Cd108 and Pd102,104,106. In addition to the ground-state band, there appear two negative-parity collective bands built on two quasineutron states. The yrast positive-parity states appear dominated by intruder states at 8+, 3044.23 keV (two-quasiproton), 10+, 4435.08 keV (two-quasineutron), and 12+, 4659.81 keV (four-quasiparticle). The results are compared to calculations from a two-quasiparticle plus slightly deformed rotor model which utilizes a variable moment of inertia.
