At present, one is faced with challenging science questions like how were the heavy elements from iron to uranium made? What is dark matter? What is the nature of dark energy? How did the Universe begin? Addressing the first question involves study of nuclei which interact with strong short-range forces. Nuclear science is primarily still a phenomenological, experimental science where one measures most nuclear quantities. Recent advancements in nuclear science allows us to study very neutron and proton rich exotic nuclei (rare isotopes) at the limits of stability. Presently a world-wide effort is put into pursuing rare isotope science to study nuclear structure, reactions and astrophysics. Experiments with the new isotopes produced will lead to a comprehensive understanding of nuclei and the origin of the elements in the cosmos. New rare isotope beam facilities as well as upgrades are coming up at ISOLDE-CERN in Switzerland, GSI in Germany, GANIL in France, RIKEN  in Japan, NSCL, ANL, HRIBF, TAMU in USA and TRIUMF in Canada. It is obvious that cutting edge experiments in nuclear science would pervade the next decade.

    Recent significant work with relevant publications:

    Search for higher excited states of 8Be* to study the cosmological 7Li problem:

    Serious discrepancy in primordial abundance of 7Li exists between observation and Big Bang

    Nucleosynthesis prediction using ηbWMAP in contrast to abundances of  2H,3,4He. This remains as 

    one of the important unresolved problems. HIE-ISOLDE facility at CERN, Geneva, Switzerland  gives unique opportunity to test it with higher 7Be beam energy and intensity. Experiment   proposed by us will be done at CERN-HIE-ISOLDE. This is the first Indian project  approved (IS 554) at  HIE-ISOLDE. Detailed Geant4 simulations are underway.

    Study of n-p pairing through two-nucleon transfer reactions: To understand n-p pairing 

    correlations we collaborated in an experiment at GANIL, Caen, France involving n-p transfer reactions on two nuclei: 48Cr, which is a candidate for n­‐p pairing correlations, and the doubly magic nucleus 56Ni which will not show any pairing effects. This will also help to understand the appearance of new magic numbers 6 and 14 far from stability. Data analysis is in progress.

    Study of resonance states of exotic nuclei: We generated an isospectral potential starting from the DDM3Y effective interaction to study quasi bound states of exotic nuclei for the first time. This resulted in an accurate determination of energy and width of resonance states.
