Hartree-Fock wave functions obtained from realistic nucleon-nucleon interaction are employed to calculate cross-sections for the reaction12
Volume 5 Issue 5 November 1975 pp 239-248 Nuclear And Particle Physics
Effective interactions of various forms incorporating central, spin-orbit and tensor dependences of two-nucleon potential are parametrized so as to give a satisfactory description of energy levels of40K. These parameters are applied to calculate energy levels of38Cl. Except for the lowest 3− level, the agreement is satisfactory.

A self-consistent procedure for calculating the particle-hole states of nuclei is given. This has been applied to the levels of16O nucleus. The particle-hole interaction is derived using Landau theory. The basis states are generated using the Brueckner many-body theory, and used in the random-phase-approximation calculation. The sensitivity of the 3- state at 6.13 MeV with the interaction is discussed, the other states being reasonably insensitive to such a choice. The effect of renormalization of the particle-hole interaction, on various states is also discussed.

The process μ−+12C→12B+
As far as the partial capture rate is concerned the use of the unitary-model operator approach wave functions for12C with
The12B(1+; g.s) recoil polarisation is found to be insensitive to the use of the unitary-model-operator-approach wave functions. When compared with the experimental data, we obtain
The total capture rate is found to be sensitive to the use of the unitary-modeloperator-approach wave functions which contain the effect of nucleon-nucleon short range correlations and we obtain a satisfactory agreement with the experiment for16O and12C, thereby revealing the importance of the effect of such correlations in the total capture rate studies.

The aim of this paper is to study the scattering of the two ground state16O nuclei, using classical microscopic approach. We have studied fusion cross-section (

Matrix element of the Galilean invariant non-relativistic reduction of the pseudoscalar-pseudovector interaction has been calculated assuming the reaction to be a direct process with bound
Volume 22 Issue 5 May 1984 pp 457-466 Nuclear Physics
Matrix element of the Gallilean invariant nonrelativistic reduction of the pseudoscalar-pseudovector interaction has been calculated for free pion absorption by a single nucleon inside the nucleus of16O. The Hartree-Fock wavefunctions obtained with the unitary-model-operator approach starting with the hard-core nucleon-nucleon interaction have been used for the π-capturing nucleon in the initial state. The initial pion distortion in the presence of nuclear field of the absorbing nucleus prior to its absorption together with the Coulomb interaction with the finite nuclear size has been taken into account. The distortion of the emitted proton in the field of the residual nucleus has also been considered. The differential cross-sections have been obtained and calculated results are compared with the previous experimental and theoretical work.

Volume 32 Issue 4 April 1989 pp 435-446 Nuclear Reactions
Classical and semi-classical microscopic approaches leading to fusion of two heavy nuclei are studied. Calculations show that the results depend strongly on the nature of the nucleon-nucleon interaction. It is also observed that there is no angular momentum window unlike in TDHF calculations.
Volume 32 Issue 6 June 1989 pp 841-844 Rapid Communication
A possible mechanism for the occurrence of nuclear fusion at room temperature is presented. Neutralization of the positive charge of the deuteron nucleus by its orbiting electron due to large enhancement of effective mass results in the vanishing of the Coulomb barrier which facilitates fusion at room temperature.
