“…In spite of this, we have recently succeeded to detect discrete γ-rays from the 12 C(n, γ) 13 C reaction for incident neutron energies in the keV region by developing a highly sensitive discrete γ-ray detection system. We have already reported on the measurement performed at neutron energies up to E n = 200 keV [2]. Here we report on the results obtained at much higher energy, E n = 550 keV.…”

“…An increasing interest has been recently developed around the low energy neutron capture reaction mechanisms induced by light nuclei in view of the importance of the related cross section for the investigation of nuclear structure properties as well as for applications in nuclear astrophysics [1][2][3][4][5][6]. In fact, it has been recently shown that (n, γ) reactions, together with their time-reversal counterpart, the Coulomb dissociation process, can provide crucial information on the structure of bound-state wave functions in light nuclei.…”

Discrete γ-rays from the neutron capture state of 13 C to its low-lying bound states have been measured using pulsed neutrons at E n = 550 keV. The partial capture cross sections have been determined to be 1.7±0.5, 24.2±1.0, 2.0±0.4 and 1.0±0.4 µb for the ground (J π = 1/2 − ), first (J π = 1/2 + ), second (J π = 3/2 − ) and third (J π = 5/2 + ) excited states, respectively. From a comparison with theoretical predictions based on the non-resonant direct radiative capture mechanism, we could determine the spectroscopic factor for the J π = 1/2 + state to be 0.80 ± 0.04, free from neutron-nucleus interaction ambiguities in the continuum. In addition we have detected the contribution of the non-resonant d-wave capture component in the partial cross sections 1 for transitions leading to the J π = 1/2 − and J π = 3/2 − states. While the s-wave capture dominates at E n ≤ 100 keV, the d-wave component turns out to be very important at higher energies. From the present investigation the 12 C(n, γ) 13 C reaction rate is obtained for temperatures in the range 10 7 −
