Abstract

We measured both the differential cross section (σ_p,p0 = d²σ/dΩdEx) and the γ-ray emission probability (Rγ(Ex) = σ_p,p0_γ/σ_p,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.
