      More Details Abstract Fulltext PDF

      A prescription has been given to calculate the two particle-one hole states, to explain the occurrence of non-normal parity states in nuclei having doubly closed shell and one extra particle. This prescription has been applied to calculate the even-parity states in41Ca and41Sc nuclei. The transition probabilities for the electro-magnetic decays of these states have also been calculated.

    • Effective two-body forces in light and medium mass nuclei

      More Details Abstract Fulltext PDF

      From the spectroscopic information provided by single particle stripping reactions, we have extracted average effective two-body interaction between nucleons in thep-, sd-, andfp- shells. Using the derived interaction parameters, we have calculated the energy centroids of the level spectra of residual nuclei obtained via single nucleon stripping reactions involving light and medium mass nuclei as targets.

    • Single particle equivalent transfer monopole sum rules involving general multishell target states

      More Details Abstract Fulltext PDF

      Monopole sum rules for single particle equivalent transfer reactions have been derived for target states where both neutrons and protons occupy the last active shell. The Pauli Principle lends some complexity to the sum rule, which is general in the sense that the inequivalent transfer situation and where the active shell has only neutron occupancy, become its special cases. Calculated values of various energy centroids have reasonable agreement with their measured counterparts.
