Abstract

Excitation functions for the

{}^{27}{(p}

,γ

)^{28}

Si reaction have been obtained over the energy range

E_{p}

=0.5–1.8 MeV. Capture was studied to the ground state

{(0}^{+}

) and the first excited state

{(2}^{+}

) at

E_{x}

=1779 keV. Detailed angular distributions were obtained in the energy region near

E_{p}

=850, 1060, 1140, and 1623 keV. The data are compared with direct capture calculations which employ a real Woods-Saxon well in both the entrance channel and the final state. The analysis of the data provides no evidence for the presence of a significant semidirect contribution.
