Description
High-spin states were populated in 54122Xe68 using the fusion evaporation reaction 96Zr(30Si, 4n) at a beam energy of 135 MeV. The level scheme of 122Xe has been extended up to spin ∼ 30ℎ. The rotational bands and band crossings in 122Xe are assigned within the framework of the cranked shell model. Three bands are found to lose their rotational character or to branch above spin ∼ 20ℎ. This is interpreted as the collective rotation of a prolate nucleus being replaced by a regime of non-collective single-particle states at high spin. Single-particle configurations are suggested for the high-spin non-collective states using modified oscillator and Woods-Saxon potentials. The development of the nuclear shape is analysed employing potential energy and total Routhian surface calculations. (author)
