RESEARCH PROGRAM AT THE LIVERMORE POOL-TYPE REACTOR
Technical Report
·
OSTI ID:4098369
A program of basic research is being conducted at the Lawrence Radiation Laboratory utilizing the Livermore Pool Type Reactor (LPTR). The LPTR is a 1-Mw reactor with provisions for further increases in power. Experimental facilities include six beam tubes, two thermal columns, one through-tube, and several source irradiation facilities. The principal physics experimenis being conducted include the investigation of crystal structure by neutron diffraction, liquid- mirror experiments, and crystal diffraction of gamma rays. A neutron crystal spectrometer was constructed. With this instrument significant new information was obtained concerning the atomic magnetic structure of antiferromagnetic iron sulfide. The liquidmirror experiment involves the measurement of the coherent scattering amplitude of hydrogen by reflecting thermal neutrons from various hydrocarbons. The reflected intensity is measured as a function of the hydrogento-carbon ratio. For precision energy measurements of gamma rays following neutron capture, a beni-quartz-crystal spectrometer is being used in the Cauchois geometry. The hinding energy of the deuteron is being measured by diffraction of the n-p capture gamma ray. The capture gamma rays of vanadium were studied with a NaI sum-coincidence spertrometer. A decay scheme was proposed for V/sup 51/ and V/sup 52/. A study of the photodisintegration of beryllium near threshold was made using radioisotopes as gamma -ray sources. LPTR experiments in the field of nuclear chemistry were mainly concerned with the fission process. In a biological investigation, minute amounts of iodine are determined by exposing specimens to a thermal neutron flux and detecting the radioactive iodine. (auth)
