Recent results pertaining to nuclear structure from neutron-induced reactions on {sup 90}Zr, {sup 193}Ir, {sup 196}Pt and {sup 238}U are presented. The data were taken using the GEANIE spectrometer comprised of 26 high-purity Ge detectors with 20 BGO escape-suppression shields. The broad-spectrum pulsed neutron source of the Los Alamos Neutron Science Center's WNR facility provided neutrons in the energy range from 0.6 to 200 MeV. The time-of-flight technique was used to determine the incident neutron energies. Results from shell model calculations for {sup 90}Zr and from IBM-2 calculations for {sup 196}Pt are generally in good agreement with the observed spectrum of excited states.
