The nuclear gamma resonance (NGR) for 238U, 236U, and 234U in the compound (UO2) Rb (NO3)3 has been established at 4.2°K following the alpha decay of PuO2 sources. The ratios of the electric quadrupole moments of these isotopes have been determined and the electric field gradient at the uranium site has been calculated from the data. The isomer shift in 234U has been measured for both PuO2 and PuA14 sources and the change in nuclear radius between the excited and the ground state has been calculated.

Energy spectra of neutrons from the 12C (3He, n)140; 27A1(3He, n)29P; 28Si(3He, n)30S; and 58,60,62Ni(3He, n)60,62,64Zn reactions have been measured at 25 MeV incident 3He energy using time-of-flight techniques. An overall energy resolution of about 1 percent for detection of 10-35 MeV neutrons provided accurate determinations of level excitations. Differential cross sections were extracted for many two particle states with up to 10 MeV excitation in the residual nuclei. By varying the beam incident angle and leaving the flight path somewhat …
