Vibrational levels are well known in atomic nuclei but despite many decades of research, some of their properties still remains elusive. In particular, the low-lying rotational bands based on the second 0+ state, which are traditionally understood as beta-vibrational bands nevertheless show properties at odds with this interpretation. For example, neutron transfer reactions in the N~90 region do not support this interpretation. An alternative is that they can better be described as a "second vacuum", or a coexisting minimum in the pairing degree of freedom. In a search for the picture that best describes the nature of the first excited 0+ states in the 160 mass region (N~90), a comprehensive analysis is being undertaken on the
data taken using the Jurogam II array in Jyvaskyla, Finland for 157Dy. The status of the analysis and results from this experiment will be discussed.
