It is pointed out that the semiclassical method of Jennings, Bhaduri and Brack for smoothing the total energy of a system of noninteracting fermions in a potential wellV(r) breaks down in the fourthorder term if this potential is nonmonotonic. This means that the method as it stands can only be used by neglecting the Coulomb force on protons. We propose a modified treatment for the fourthorder term which appears to be entirely satisfactory.

We have calculated the groundstate occupancies of various nuclei in the spectroscopic space of upperfp shell andg_{9/2} orbit using spectral distribution methods. The modified fully renormalised KuoBrown interaction has been used. The calculated values have been compared with the experimental results.

The surface diffuseness of deformed and rotating nuclei has been studied using the energy density formalism. It is shown that the surface diffuseness exhibits an anisotropy. This anisotropy in surface diffuseness can result in an anisotropic charged particle emission from highly spinning nuclei as has been seen in some recent experiments.

The hot rotating compound systems formed in heavy ion collisions are studied using the statistical theory with a view to determine the spin and temperature dependence of nuclear shapes. Shape transitions are observed for these systems at particular spin values. The neutron and proton separation energies for heavier high spin systems have been evaluated. Results are presented for

Phaseshiftequivalent potentials are used to study the sensitivity of triton binding energy (E_{T}) to the offshell behaviour of twonucleonT matrix in a translationallyinvariant basis of harmonic oscillator wavefunction. For a smaller value of inverse range parameterλ (1.95 fm^{−1}), which is close to the attractive range of our model potential, a 21% variation in the triton binding energy is obtained. For the other value ofλ an offshell variation of about 28% inE_{T} is obtained.

The structure of the selenium nuclei in the regionA = 70 is studied using our deformed configuration mixing (DCM) shell model based on HartreeFock states. An effective interaction given by Kuo and modified by Bhatt is used. An attempt is made to understand the coexistence of shapes in selenium nuclei.

A new derivation of the inverse energyweighted sumrules is given by applying the spectral distribution methods to the RayleighSchrodinger perturbation theory. The scalar space result is then extended to the configurations. This is applied to obtain corrections to the groundstate energy estimates when the effective interaction is approximated by a model Hamiltonian obtained by taking linear combinations of various parts of the pairing and the Q.Q operators.
