Query: Level densities and thermodynamical quantities of heated 93-98Mo
  isotopes   Level densities for 93-98Mo have been extracted using the (3He,alpha gamma)
and (3He,3He' gamma) reactions. From the level densities thermodynamical
quantities such as temperature and heat capacity can be deduced. Data have been
analyzed by utilizing both the microcanonical and the canonical ensemble.
Structures in the microcanonical temperature are consistent with the breaking
of nucleon Cooper pairs. The S-shape of the heat capacity curves found within
the canonical ensemble is interpreted as consistent with a pairing phase
transition with a critical temperature for the quenching of pairing
correlations at T_c ~ 0.7-1.0 MeV.
