Application of Nilsson model for deformed nucleus in relativistic heavy ion collisions
For spherically symmetric nucleus (Au or Pb), Wood-Saxon (WS) distribution proves to be highly manoeuvrable and aptly suitable in giving nucleon distribution within a nucleus. Incorporating shape modification in WS, earlier attempts were made to explain observables in deformed nucleus such as Uranium(U). Although the shape of distribution remains consistent, the Modified Wood Saxon (MWS) overestimates the particle multiplicities. In this work, we use an alternate approach known as Nilsson model, to explain U+U collisions at $\sqrt{S_{NN}}$ = 193 GeV of RHIC. We have implemented the formalism in HIJING model to calculate charged particle multiplicity and pseudo-rapidity distributions. The model describes the experimental data more closely than WS/MWS and thus is more suitable to study deformed nucleus within this model formalism.
