Title: Observation of negative-parity high spin states of {sup 126}Cs

Abstract

The nucleus {sup 126}Cs was investigated by means of in-beam {gamma}-ray spectroscopy techniques using the Nordball detector system at the Niels Bohr Institute. Excited states of {sup 126}Cs were populated via the {sup 116}Cd({sup 14}N, 4n){sup 126}Cs reaction at a beam energy of 65 MeV. The {sup 126}Cs level scheme was considerably extended, especially at negative parity and about 40 new levels and 70 new transitions were added into the level scheme. The previously reported negative-parity rotational bands, built on {pi}g{sub 7/2}x{nu}h{sub 11/2},{pi}d{sub 5/2}x{nu}h{sub 11/2},{pi}h{sub 11/2}x{nu}g{sub 7/2}, and {pi}h{sub 11/2}x{nu}d{sub 5/2} configurations, have been extended and evolve into bands involving rotationally aligned ({pi}h{sub 11/2}){sup 2} and ({nu}h{sub 11/2}){sup 2} quasiparticles. Two new rotational bands have been tentatively assigned the {pi}h{sub 11/2}x{nu}s{sub 1/2} and {pi}g{sub 9/2}x{nu}h{sub 11/2} configurations, respectively.
