Phase-function method for complex potentials
A K Jana J Pal T Nandi B Talukdar
We consider the scattering problem for absorptive interactions within the framework of phase-function method. A Green’s function approach is used to derive the phase equation. As a case study we apply the algorithm presented on a shallow α-α potential, the real and imaginary parts of which have been deduced from experimental data. The real and imaginary parts of the

The 15 UD pelletron at NSC has been operational and performed well during the last 11 years. There have been major modifications performed for upgradation of pelletron system over this period. Major upgradations which have been implemented are new resistor network system for voltage gradient, doublet to singlet unit conversion for accelerator units, turbopump based gas stripper system etc. In addition accelerator mass spectroscopy program has also been started. A new multi-cathode source, Wien filter etc. have been procured and will be added soon in the system. An overview of the most significant upgradations undertaken and other activities for the system are being reported in the present paper.

Search for a viable nucleus–nucleus potential in heavy-ion nuclear reactions
T NANDI D K SWAMI P S DAMODARA GUPTA YASH KUMAR S CHAKRABORTY H C MANJUNATHA
We have constructed empirical formulae for the fusion and interaction barriers using a large number of experimental values
chosen randomly from the literature available till date. The obtained fusion barriers have been compared with different model
predictions based on the proximity, Woods–Saxon and double folding potentials along with several empirical formulas,
time-dependent Hartree–Fock theories and experimental results. The comparison allows us to find the best model,
which is nothing but the present empirical formula only. Most remarkably, the fusion barrier and radius show excellent
consonance with the experimental findings for the reactions meant for the synthesis of super heavy elements also. Furthermore,
it is seen that substitution of the predicted fusion barrier and radius in classic Wong formula (Wong,
