Total cross sections of nuclei for 280 Mev neutrons.

The measurement of 28O-Mev neutron cross sections of various nuclei is described. The neutron beam used results from 340-Mev protons in the 184-in. cyclotron striking a 2-in. Be target. The neutron detector consists of a double coincidence anthracene scintillation counter telescope which counts recoil protons scattered at 15 deg from a paraffin cylinder placed in the collimated neutron beam. A 2-in. Cu absorber placed between the counters assures that only protons of energy greater than 250 Mev are counted. The cross sections for all nuclei measured from Li to Pb are smaller than the corresponding cross sections measured at 90 Mev by factors between 0.5 and 0.6.

Photoelectronic properties of zinc phosphide crystals, films and heterojunctions : quarterly progress report no. 6 for the period July 1 - September 30, 1980 /

The purpose of this research program is to investigate the photoelectronic properties of zinc phosphide (Zn₃P₂ in single crystal form, in thin-film form, and in heterojunctions in which Zn₃P₂ forms one of the elements. This research will be directed toward understanding the role of crystalline defects and impurities in Zn₃P₂, the nature of the electronic charge transport in single crystal and thin-film material, and the properties of photovoltaic heterojunctions involving Zn₃P₂. The scope of the program extends from basic investigations of materials properties on single crystals to the preparation and characterization of all-thin-film heterojunction divices. One of the principal motivations behind this research program is the realization that Zn₃P₂ is a relatively uninvestigated yet ideal component for photovoltaic heterojunction use in solar energy conversion. The proposed program will concentrate on the basic materials problems involved with Zn₃P₂, providing the kind of information needed for other more developmental programs directed toward actual practical cells.
