Περίληψη:
Single-nucleon transfer reactions are processes that selectively probe
single-particle components of the populated many-body nuclear states. In
this context, recent efforts have been made to build a unified
description of the rich nuclear spectroscopy accessible in heavy-ion
collisions. An example of this multichannel approach is the study of the
competition between successive nucleon transfer and charge exchange
reactions, the latter being of particular interest in the context of
single and double beta decay studies. To this extent, the one-proton
Ti-48 (O-18, F-19)(47) pickup reaction Sc at 275 MeV was measured for
the first time, under the NUMEN experimental campaign. Differential
cross-section angular distribution measurements for the F-19 ejectiles
were performed at INFN-LNS in Catania by using the MAGNEX large
acceptance magnetic spectrometer. The data were analyzed within the
distorted-wave and coupled-channels Born approximation frameworks. The
initial and final-state interactions were described adopting the Sao
Paulo potential, whereas the spectroscopic amplitudes for the projectile
and target overlaps were derived from shell-model calculations. The
theoretical cross sections are found to be in very good agreement with
the experimental data, suggesting the validity of the optical potentials
and the shell-model description of the involved nuclear states within
the adopted model space.
