Study of collectivity in {sup 111}In
- and others
The high-spin structure of {sup 111}In has been investigated with {gamma}-ray spectroscopic methods using the {sup 96}Zr({sup 19}F,4n) reaction. A thin target experiment using an 85 MeV beam provided by the Chalk River TASCC facility yielded 50 million {gamma} - {gamma} coincidence events from the 8{pi} spectrometer, whereas a backed target experiment using a 72 MeV beam provided by the SUNY Stony Brook LINAC facility yielded 150 million events from the Stony Brook BGO-suppressed Ge spectrometer. As initial report on these {sup 111}In data presented the discovery of the first {pi}h{sub 11/2} intruder band found below the Z=50 shell gap. A complete level scheme has now been established utilizing the full data set in the form of symmetrized and angular correlation (DCO) matrices. Decoupled and strongly coupled bands have been observed with possible interpretations involving, respectively, the {pi}g{sub 7/2}{circle_times}{pi}g{sup {minus}2}{sub 9/2} configuration and the {pi}g{sup {minus}1}{sub 9/2} orbital coupled to the deformed 2p2h core state of {sup 112}Sn.
