[en] Recently, Gupta and Hamilton have pointed out that the absolute slopes of the kinetic MoI versus spin I, using expression, represents only the deformation of the core, not the change in nuclear structure with spin. This is important, especially for near spherical nuclei. Instead, it is the change in slope with spin I, which represents the variation of nuclear structure with spin. Here we illustrate this aspect of nuclear structure by looking at the correspondence of the variation of kinetic MoI with spin and the value of 'b' in the power index formula
