Title: Coulomb breakup of neutron-rich isotopes of light nuclei

Abstract

The effects of higher order multipole transitions, in particular, E2 and E1-E2 interference, in the Coulomb dissociation of neutron-rich nuclei {sup 11}Be, {sup 14}B, {sup 15}C, and {sup 19}C on Pb targets at energies of 72, 86, 550, and 77 A MeV, respectively, within the framework of the eikonal-approximation approach are studied. The main steps involved in the derivation of the explicit expressions corresponding to dipole, quadrupole, and dipole-quadrupole-interference terms are outlined. The calculations reveal that the contribution of E2 transitions to the total cross section is finite but small, while that ofE1-E2 interference is nil.Nevertheless, the E1-E2 interference term introduces small distortions in the peak of the relative-energy spectrum. The calculated results are compared with the corresponding data and the comparison favors a value of 0.530 MeV as the ground-state binding energy of {sup 19}C.
