| 英文摘要 | The nonresonant component of radiative neutron capture reactions is parametrized at low energies by a polynomial of second degree. The potential model is first used to reproduce experimental data below 1 MeV with the help of spectroscopic factors. The fits are found sensitive to the scattering length of the initial s or p waves. The coefficients of a Taylor expansion are then calculated by resolution of the Schrodinger equation and its energy derivatives at energy zero. Such theory-guided parametrizations are derived for neutron capture by (7)Li, (12)C, (14)C, (16)O, and (18)O. When the capture proceeds from the s wave to a weakly bound state, a Pade-like parametrization better approximates the potential-model results. |
