Parametrization of low-energy cross sections for nonresonant neutron capture

Determining the7Li(n,γ) cross section via Coulomb dissociation of8Li

“…The only other case where the (γ,n) Coulomb dissociation cross sections were compared with directly measured cross sections was the system 14 C(n,γ) 15 C which involved predominantly the capture of p-wave neutrons [9]. The anticipated deviation from the 1/v behavior at higher neutron energies was observed and could be fitted within the parameterization of Baye [50] and Wang et al [41]. The data also agree well with the results of the low-energy effective field theory calculations by Rupak and Higa [43].…”

“…All models predict the observed deviation from the 1/v dependence of the cross section towards higher energies. The potential models for direct radiative capture by Nagai et al [16] and Wang et al [41] slightly overpredict the magnitude of the deviation. Huang et al described the radiative proton-and neutron-capture for all available data on light nuclei with a simplified twobody treatment of the capture process [42].…”

“…The deviation from the 1/v dependence has previously been included in the parameterization of the cross section as [41,50] …”

“…In addition to the models described in the experimental papers [12,15,16], many theoretical calculations have described the available data (see for example [41][42][43][44][45][46][47][48]). …”

Description of the proton and neutron radiative capture reactions in the Gamow shell model

“…Eqs. (45) are solved iteratively to determine the equivalent potential, the source term, and the mutally orthogonal radial wave functions w c (r). Starting point for solving these equations is provided by a set of radial channel wave functions {w c (r)} obtained by the diagonalization of GSM-CC equations (37) in the Bergen basis of channels.…”
