Description

An analysis of cross sections of elastic scattering of ${}^{17}$F on
${}^{12}$C, ${}^{14}$N, ${}^{58}$Ni, and ${}^{208}$Pb nuclei at energy 170
MeV and on ${}^{208}$Pb at various energies is carried out by using
the microscopic optical potentials (OPs). The proton and neutron
density distributions of the exotic nucleus ${}^{17}$F are computed
in the framework of microscopic models. The real part of the OP is
calculated by a corresponding folding procedure accounting for the
anti-symmetrization effects, while the imaginary part is obtained
on the base of the high-energy approximation [1]. In the hybrid
model of the optical potential developed and explored in our
previous works [2,3] the only free parameters are the depths of
the real and imaginary parts of the OPs obtained by fitting the
experimental data. A good agreement of the theoretical results
with the available experimental data is achieved pointing out
clearly to a peripheral character of the scattering.
