Resumo
Background: Nucleon transfer reactions are selective tools for nuclear physics investigations. The theoretical
and computational limits affecting in the past their data analysis could be nowadays surmounted thanks to the
advent of methods with refined approximations and constraints, even when heavy-ion collisions are considered. Purpose: Modern microscopic calculations of heavy-ion-induced transfer reactions combined with precise
experimental data offer the chance for accurately testing different reaction models as well as the nuclear structure
description of the involved nuclear states. Method: Single proton and neutron transfer reactions were measured with theMAGNEX magnetic spectrometer
for the 18O+40Ca system at 15.3A MeV. Excitation energy spectra and angular differential cross section
distributions were extracted. The experimental results are compared with theoretical calculations performed in
distorted wave and coupled channel Born approximation. The use of a coupled channel equivalent polarization
potential to effectively describe the coupling effects affecting the initial state interaction is also considered.
Spectroscopic amplitudes derived from a large-scale shell model with appropriate interactions adapted for the
involved nuclei are employed. Results: Our theoretical calculations are in good agreement with experimental data, without the need for any
scaling factor, validating the adopted reaction and nuclear structure parameters. Moreover, under the present experimental conditions, a weak dependence of the obtained results on the choice of the reaction models was
observed. Conclusions: The good agreement between experimental and theoretical results validates the reliability of
the parameter sets entering the calculations. They are extracted from or tested in complementary analyses of
other reaction channels under the same experimental conditions. Such a multichannel approach represents the
best option to pursue a solid, comprehensive, and model-independent description of the single-nucleon transfer
reactions. The successful description of the present one-nucleon transfer data is also propaedeutic to the accurate
assessment, under the same theoretical description, of higher-order transfer processes, like the sequential nucleon
transfer mechanisms which are in competition with the direct charge exchange reactions.
