This article introduces software called Phonon Explorer that implements a data mining workflow for large datasets of the neutron scattering function, S(Q, ω), measured on time-of-flight neutron spectrometers. This systematic approach takes advantage of all useful data contained in the dataset. It includes finding Brillouin zones where specific phonons have the highest scattering intensity, background subtraction, combining statistics in multiple Brillouin zones, and separating closely spaced phonon peaks. Using the software reduces the time needed to determine phonon dispersions, linewidths, and eigenvectors by more than an order of magnitude.

Gamma rays following the interaction of 14.1-MeV neutrons with natural samples of Na, Mg, S, Si, Mn, and Fe have been studied using an associated particle time-of-flight technique. The analysis has revealed several previously unreported gamma rays following neutron scattering and neutron-induced reactions. Assignments have been made for the possible reaction processes and transition modes.
