Correlating yrast isomers and shape co-existence in ¹⁵²Dy

Recently it has been demonstrated for ¹⁵³Ho that the study of yrast isomers can be useful to follow the evolution of the structure of a nucleus with increasing excitation energy and spin. In the excitation pattern several twists and turns were observed as a function of spin, which indicated several changes in structure. Interestingly most of the bends are associated with isomers. In this work, it has been also demonstrated that the excitation pattern of ¹⁵³Ho follows the core nucleus ¹⁵²Dy
