Intermediate-energy nuclear physics. Task W. Technical progress report, February 1-October 1, 1983. Part II

This report summarizes work carried out at the Nuclear Physics Laboratory of the University of Colorado from February 1, 1983 to October 1, 1983 under DOE Contract DE-AC-81ER-40016 (Task W). A large fraction of this work was carried out at the University of Colorado including neutron detector modelling, design, construction and testing. Analysis of data, theoretical calculations, scattering chamber design, and analysis of the capabilities of the accelerator and time-of-flight spectrometer at Los Alamos were also done at Colorado. Development of the flight path, detector hut, light fiber signal link, data acquisition system, target wheel and beam line were done at Los Alamos largely by Los Alamos personnel. Data acquisition was carried out at Los Alamos. Observation of Fermi and Gamow-Teller strength in the 800 MeV 13C(p,n)13N reaction is reported
