M1 bands and intruder bands in {sup 113}In
- Tata Institute of Fundamental Research, Bombay 400 005 (India)
High spin states in {sup 113}In have been established up to 6.2 MeV in excitation energy and to a tentative spin of (43/2{sup {minus}}) through the reaction {sup 110}Pd({sup 7}Li, 4n){sup 113}In at a beam energy of 40 MeV. In-beam measurements involved {gamma}-{gamma} coincidences, angular distribution of emitted gamma rays, and directional correlation of oriented states. M1 bands consisting of {Delta}I=1 dipole transitions have been observed. Possible quasiparticle configurations suggest that these bands are similar to the shears bands observed in Pb nuclei. Two intruder bands based on the {pi}h{sub 11/2} orbital and {pi}g{sub 7/2} orbital have been observed. Results of the total Routhian surface and cranked shell model calculations are compared with the experimental data. Alignment features of the intruder bands in the N=62 and 64 isotones are discussed. {copyright} {ital 1997} {ital The American Physical Society}
