“…Figures 2 and 3 show the partial decay schemes for 101,102 Ru and 98,99 Mo deduced in the current work. Where statistics allowed, the spin assignments were made on the basis of DCO ratios and comparison with the published decay schemes for these nuclei [8,12,22,24].…”

Nuclei below the Z = 50 magic shell gap with A∼100 show a wide variety of structural phenomena. These include excellent examples of vibrational collectivity at low-spins, which give way to more rotational-like excitations with increasing angular momentum. In this paper we present recent results from an experiment performed at Yale to study the yrast evolution of states in 98,99 Mo and 101,102 Ru. Although the high-spin data is consistent with predictions from rotational model theories, we propose a simple presciption to distinguish between vibrational and rotational regimes of angular momentum generation. When applied to the nuclei of interest, a clear picture emerges of how these two mechanisms of collective spin generation compete in this region.
