High energy γ rays fromN14+nat

Abstract

The absolute cross section and angular distributions for p-ray production in the reaction N + " 'Ag at 35 MeV/nucleon have been measured. Calculations of the expected p-ray yield using an enhanced version of the nucleon exchange transport model have been performed. It has been observed that use of a sharp ground state momentum distribution in the p-ray calculations does not lead to reproduction of the experimental yields. Dift'use momentum distributions have been incorporated into the model, and the calculations with these momentum distributions give good agreement with experimental yields. Similar calculations have been performed for the production of preequilibrium neutrons and protons for the same system. PACS number(s): 25.70.z

Constraints on the time scale of nuclear breakup from thermal hard-photon emission

“…The KVI "Forward Wall"(FW) [23], consisted of 92 plastic scintillator phoswiches, detects and identifies LCP and IMF (up to Z≈15) emitted in the forward direction. In our experimental setup, this detector was placed downstream 74 cm away from the target covering the forward hemisphere behind the SSD, 2.5 • ≤ θ ≤ 25 • and the whole azimuthal range.…”

High energy gamma rays from p+X, X=Cu, Ag, Au at 34 MeV

“…The first was to complement a series of heavy ion experiments [1,2], in order to understand the production mechanism of high energy γ rays at intermediate energies. The argument for this motivation is as follows.…”
