Abstract
Differential cross sections of elastic scattering of 12,14 Be on 12 C and protons are analyzed within the microscopic model of the optical potential (OP). The microscopic OP consists of the double folding real part and the imaginary part which is constructed using the high energy approximation theory. The OP depends on the nuclear density distributions of 12,14 Be and thus, their microscopic models are tested in our study.
Highlights
The present study aims to analyze the elastic scattering of the neutron-rich isotopes 12,14 Be on 12 C and proton targets by using of microscopically calculated optical potential (OP), where the nucleon density distributions of the exotic nuclei 12,14 Be are being of the main physical interest
Where the ρSF is determined by Eq (6) with radius R=2.275 fm and diffuseness a =0.393 fm and the surface term ρ(1) is calculated via the 1st derivative of ρSF. The parameters of this density were obtained in [12] by fitting to the eA scattering data. It was suggested in [1] and [2] that the experimental data should be considered as quasielastic scattering, i.e., the contribution of inelastic channels related to excitations of the low-laying collective states of a nucleus, should be accounted for
The inelastic OP was calculated via the derivative of the microscopic OPs: U inel = - R · dU/dr, where U is microscopic OP in the form (5), Ris the potential radius
