Modifications tc the accelerator included installation of a switching magnet that provides five beams and of photoelectric klystron spark detectors. Solution of the monoenergetic transport equation in slab geometry showed that a real time decay constant exists for all slab thicknesses in die-away experiments. Relations were also derived that permit comparison of theoretical die-away parameters with experimental results. Water spectra were calculated by the Mass- 1 gas and Nelkin models and were compared with experimental results. An examination of the validity of various approximations used to solve the monoenergetic time dependent transport equation demonstrated that the variational method has the advantage that it leads to the correct asymptotic time dependent characteristic in the thin slab limit. Pulsed-chopper measurements of the asymptotic scalar and surface spectrum for three multiplying assemblies were made. Improved resolution and back round reduction were achieved in low-energy neutron inelastic scattering experiments; good data were obtained on vanadium. for incident energies up to 1.7 ev. Data were also obtained for polyethylene at incident energies of 0.215 and 0.625 ev. (D.C.W.)
