Abstract
Differential cross sections for nonresonant radiative capture of low energy protons (E p = 1,348 keV and 1,370 keV) by23Na nuclei exhibit features pointing to the virtual excitation of the giant dipole resonance (GDR) mode. Theoretical analysis carried out within the framework of the direct — semidirect capture model reveals an enhanced coupling of the GDR with the incident protonf-wave consistent with the microscopic structure of the GDR in thes-d shell nuclei.
