“…Response functions of the LCS γ-ray beams were measured with a 3.5 × 4.0 LaBr 3 (Ce) (LaBr 3 ) detector. The energy profiles of the LCS γ-ray beams were determined by best reproducing the response functions in Monte Carlo simulations with a GEANT4 code [22,23] that incorporates the kinematics of the LCS process, including the electron beam emittance [24,25]. The incident LCS γ-ray beams are shown in Fig.…”

Photoneutron emission cross sections were measured for 13 C below 2n threshold using quasimonochromatic γ-ray beams produced in laser Compton-scattering at the NewSUBARU synchrotron radiation facility. The data show fine structures in the low-energy tail of the giant-dipole resonance; the integrated strength of the fine structure below 18 MeV is intermediate among the past measurements with bremsstrahlung and the positron annihilation γ rays. We compare the photoneutron emission data with the TALYS statistical model calculation implemented with the simple modified Lorentzian model of E1 and M 1 strengths. We also compare the total photoabsorption cross sections for 13 C with the shell model and antisymmetrized molecular dynamics calculations as well as the statistical model calculation. We further investigate the consistency between the present photoneutron emission and the reverse 12 C(n,γ) cross sections through their corresponding astrophysical rate.
