Shape coexistence and band terminations in the I ∼ 60 spin range

High-spin bands in nuclei with A ∼ 130-170 are interpreted using the cranking formalism where pairing is either neglected or included in the cranked Nilsson-Strutinsky-Bogoliubov (CNSB) formalism. The advantage of the unpaired formalism is that different rotational bands can be understood in a much more detailed way. The combination of these two methods is a very powerful way to get a detailed understanding of observed high-spin states. In this talk, we will point out the difficulty to distinguish between strongly deformed configurations and configurations approaching termination. It is of special interest that terminating states with up to 18 particles or particles + holes outside closed shells have been observed and more of them should be reasonably straightforward to observe. The possibility to exhaust the spin content in major shells will be discussed. This document is composed of an abstract and the slides of the presentation. (authors)
