Analysis of Coulomb Breakup Reactions of 19C on heavy Targets

Abstract

Abstract:         The Coulomb breakup reactions ¹⁸¹Ta(¹⁹C, ¹⁸C+n)¹⁸¹Ta and ²⁰⁸Pb(¹⁹C, ¹⁸C+n)²⁰⁸Pb has been investigated at 88AMeV and 67AMeV beam energies respectively within the theoretical framework of eikonal approximation with a motive to estimate  the relative contribution of higher order multipole transitions, especially of electric quadrupole and dipole-quadrupole interference terms. The results so obtained reflect the finite contribution of electric quadrupole terms at higher relative energies while the dipole-quadrupole interference terms show their presence through longitudinal momentum distribution of core.
