Abstract
Measurements of cross sections and analyzing powers are examined for polarized proton capture on , , , , , , and at energies which cover the giant dipole resonance region. These data are used to extract the relative amplitudes and phases of the contributing -matrix elements. A typical result exhibits two solutions. Calculations using the direct (or a direct-semidirect) capture model appear to provide a means for choosing the physical solution.
NUCLEAR REACTIONS: , , , , , , ; measured and over energy region of the giant dipole resonance. Deduced -matrix amplitudes and phases. Compare results to direct-semidirect model calculations.
