Query: Shape Coexistence in Hot Rotating 100 Nb   Temperature and angular momentum induced shape changes in the well deformed
100 Nb have been investigated within the theoretical framework of Statistical
theory combined with triaxially deformed Nilson potential and Strutinsky
prescription. Two shape coexistence, one in the ground state of 104 Nb between
oblate and triaxial shapes and another one between oblate and rarely seen
prolate non-collective shapes in excited hot rotating 100 Nb at the mid spin
values around 14-16h are reported for the first time. The level density
parameter indicates the influence of the shell effects and changes drastically
at the shape transition. The band crossing is observed at the sharp shape
transition.
