“…Both the measurements [15] and two body model calculations in Ref. [5]- [15] show a tendency for σ not to increase at given U as fast with A near A=30 as the rigid body prediction (A 7/6 ). This agrees with the predictions in this mass region from calculations presented in Fig.…”

“…Other techniques have also been used to calculate the spin cutoff parameter. Authors have used [5,[15][16][17][18][19][20] techniques which use the full two-body interaction to calculate both level densities and spin cutoff parameters. These have been concentrated in a mass region below A=65 but at least one paper presents calculations near A=160 [20].…”

The spin cutoff parameter determining the nuclear level density spin distribution ρ(J) is defined through the spin projection as < J 2 z > 1/2 or equivalently for spherical nuclei, (It is needed to divide the total level density into levels as a function of J. To obtain the total level density at the neutron binding energy from the s-wave resonance count, the spin cutoff parameter is also needed. The spin cutoff parameter has been calculated as a function of excitation energy and mass with a super-conducting hamiltonian. Calculations have been compared with two commonly used semi-empirical formulas. A need for further measurements is also observed. Some complications for deformed nuclei are discussed. The quality of spin cut off parameter data derived from isomeric ratio measurement is examined.
