Abstract: Nuclear reactions that produce neutrons have broad impacts in both nuclear astrophysics and applied nuclear physics. α-particle induced reactions on light nuclei provide the neutrons that fuel the creation of the heavy elements in a variety of stellar environments, produce background signals for large volume neutrino detectors, and play a pivotal role in the evolution of stored nuclear material. Yet many of these reactions remain poorly measured due in part to the experimental difficulties surrounding neutron detection.

In this talk, I will present a little utilized method of neutron spectroscopy that has made great strides in its practical usage in re- cent years. Further, I will discuss an alternate method of measuring many neutron producing reactions that populate excited states in the residual nucleus by instead measuring secondary γ-rays and the interpretation of their angular distributions in the phenomenological R-matrix framework.
