SEMI-ANNUAL SUMMARY RESEARCH REPORT IN PHYSICS FOR JANUARY THROUGH JUNE 1957

PDF Version Also Available for Download.

Description

Deviations from the allowed spectrum shape observed in P/sup 32/ beta - decay are discussed. Coincidence data taken on Yb/sup 169/ and Tb/sup 160/ are reviewed. The directional correlation function for the 357 to 82 kcv gamma cascade in Cs/sup 133/ following Ba/sup 133/ electron capture decay was determined. The detection of trace oxygen impuritics in metals by the beta activity from x-ray bombardment appears feasible. Results obtained in tests of this mcthod are reported. A pulse heating method for measuring the high- temperature specific heats of metals was developed and applied to Fe in the temperature range 25 to ... continued below

Description

Deviations from the allowed spectrum shape observed in P/sup 32/ beta - decay are discussed. Coincidence data taken on Yb/sup 169/ and Tb/sup 160/ are reviewed. The directional correlation function for the 357 to 82 kcv gamma cascade in Cs/sup 133/ following Ba/sup 133/ electron capture decay was determined. The detection of trace oxygen impuritics in metals by the beta activity from x-ray bombardment appears feasible. Results obtained in tests of this mcthod are reported. A pulse heating method for measuring the high- temperature specific heats of metals was developed and applied to Fe in the temperature range 25 to 1000 deg C. The results of electrical resistivity measurements made on Ni and Ni-alloys at temperatures between 25 and 1000 deg C are plotted. Discussions of the semiconducting properties of Mg/sub 2/Si and Mg/ sub 2/Ge single crystals are included. (For preceding period see ISC-833.) (D.E.B.)
