DESCRIPTION:Speakers: Ahmed Amer (National Research Nuclear University “
 MEPhI”)\, Ahmed Hammad  Amer1\,2\,*  (1National Research Nuclear Univers
 ity “MEPhI”\, Moscow\, 115409\, Russia 2Joint Institute for Nuclear Re
 search\, Dubna\, 141980\, Russia * Faculty of Science\, Tanta University\,
 Tanta\, Egypt)\nIn the present research\, the analysis of experimental ela
 stic scattering angular distributions data of alpha particles on 28Si nucl
 ei carried out using SFRESCO computational code in the energy range from 1
 8 to 240 MeV. The data were analyzed using phenomenological Woods–Saxon 
 (WS) potential within the context of the optical model (OM). We created th
 e real potentials in the double-folding (DF) calculations by folding the n
 ucleon- nucleon (NN) interaction into nuclear matter density distributions
  of alpha projectile and the 28Si target. A density dependent version of M
 3Y interactions (CDM3Y6)\, which based on the G-matrix elements of the Rei
 d (NN) potential\, have been used. The imaginary potentials kept fixed for
  each energy during (DF) search as obtained from phenomenological imaginar
 y (WS) potential part. The renormalization factor of folded potential Nr h
 ave been extracted at all energies. we have investigated the observed phen
 omena of anomalous large angle scattering (ALAS)at low energies and rainbo
 w-like structure scattering at high energies for α+28Si nuclear system. T
 he total reaction cross sections σ_R\, the (real and imaginary) potential
  volume integrals (J_V and J_W) as well as the χ^2/N values have been obt
 ained for fourteen energies. The theoretical (OM) and (DF) calculations of
  angular distributions in the entire angular range are in a good agreement
  with the experimental data.\n\nhttps://indico.particle.mephi.ru/event/35/
