Determination of the radiative neutron capture rate on $^{14}$C via indirect methods

ORAL

Abstract

$^{14}$C(n,$\gamma )^{15}$C is being used as a test case in the development of an indirect method to determine neutron capture cross sections on neutron-rich unstable nuclei at astrophysical energies. Our approach combines information about the peripheral component of the reaction (ANC) with information from the interior contribution (spectroscopic factor). The ANC for $^{15}$C has been determined using HI neutron transfer with a 12 MeV/nucleon $^{14}$C beam on a $^{13}$C thin foil target. The spectroscopic factor will be determined using $^{14}$C(d,p) in forward kinematics with a incident deuteron energy of about 60 MeV. Both experiments were done with the high-resolution MDM spectrometer of Texas A{\&}M University.
