| 英文摘要 | Radiative neutron capture reactions play an important role in nuclear astrophysics. In some cases direct neutron capture reaction studies are not possible and neutron transfer reactions have been suggested as a surrogate approach. We have performed a detailed study of the Mg-25(d, p) Mg-26 reaction at a beam energy of 56 MeV as a surrogate reaction to the radiative neutron capture reaction Mg-25(n, gamma) Mg-26. A large number of neutron bound and unbound states between 10.6 and 12.1 MeV excitation energy in Mg-26 were observed. Angular distribution analysis provided information about the orbital momentum transfer populating these levels. The comparison with resonances observed in the Mg-25(n, gamma) Mg-26 reaction indicate that different levels in Mg-26 are being populated through the two reaction mechanisms, causing substantial discrepancies in the reaction-rate prediction. This result demonstrates that neutron transfer reaction studies may not necessarily lead to reliable predictions for neutron capture reaction rates. |
