Projects

  • Project 1: Breakup of loosely bound nuclei

In this project, we mainly focus on

  • The study the interplay of the multipole interferences and the continuum-continuum cou-plings for different reactions. This will shed more light into a more clear understanding of effects the multipole transitions and continuum-continuum couplings in the breakup process.The importance of the diagonal and off-diagonal continuum-continuum couplings on various breakup channels will also be investigated. Separate total, Coulomb and nuclear breakups will be considered for a better understanding of the role of the nuclear breakup contribution in a Coulomb-dominated breakup reaction.
  • Breakups of 6Li, 7Li, 8Be, 7Be, 11Be loosely bound nuclei on different target masses. Here we aim to investigate the role of the fragment mass and charge in the breakup process. The effects of the projectile resonances and binding energy will also be considered. This provides a good opportunity to investigate the differences between the breakup of loosely bound and more stable projectiles.
  • Project 2: Structure of light hypernuclear systems

In this project the three-body cluster models for light hypernuclei, lambda He6, Lambda Li8, Lambda Be8, which are of current interest. We will calculate bound state properties, scattering parameters as well resonances, using the Lagrange-mesh method and Jost functions. These are simple methods and have been proven to be accurate, and numerically very simple to implement.

  • Project 3: Fusion and multinucleon transfer reactions

This project will mainly focus on studying the effects of nucleon transfer channels on fusion cross sections for incident energies below, around and above the Coulomb barrier. To this end, theoretical methods like the empirical channel coupling model, the Langevin equations, among others will be used.
