Abstract

Direct-semidirect radiative-capture calculations are compared to new detailed

{}^{14}C (p_{pol}, γ_{0}) {}^{15}N

measurements in the giant-dipole-resonance region. The calculations provide a good description of the data by including only direct

E 2

and direct plus collective

E 1

. The experimentally determined

E 2

cross section exhausts (6.8±1.4)% of the isoscalar sum rule and shows no sign of a resonance.
