Abstract

We measured both the differential cross section (σp,p0 = d2σ/dΩdEx) and the γ-ray emission probability (Rγ(Ex) = σp,p0γp,p0) from the giant resonances excited by 12C(p,p0) reaction at 392 MeV and 0, using a magnetic spectrometer and an array of NaI(Tl) counters. The absolute value of Rγ(Ex) was calibrated by using the well-known γ-ray emission probability from 12C(15.11 MeV, 1+, T = 1) and 16O(6.9 MeV, 2+, T = 0) states within 5% uncertainty. We found that Rγ(Ex) starts from zero at Ex = 16 MeV, increases to a maximum of 53.3±0.4±3.9% at Ex = 27 MeV and then decreases. We also compared the measured values of Rγ(Ex) with statistical model calculation based on the Hauser-Feshbach formalism in the energy region Ex = 16-32 MeV and discussed the features of γ-ray emission probability quantitatively.
