Zr9602 (isotopic concentration 90 per cent) was irradiated by slow neutrons in the Oak Ridge pile. The half-period of the niobium daughter element, chemically separated from zirconium, was found to be 72.1 ~ 0.7 rain. and that of Zr 97 to be 17.0 + 0.2 hr.

Using a source of As v4 in the form of arsine gas, a resonance fluorescence effect from the 635 kev level in Se v4 has been observed. Due to the small abundance of Se v4 (0.87 per cent), the effect is not very pronounced and the mean life of 6 X 10 -12 second, calculated from the magnitude of the re

observations have been made over temperatures between 900" and 1300" C. The initial conductance is found to obey Ohm's law; its temperature dependence is of the usual exponential form with an activation energy of 1.1 volt. Optica1 absorption measurements show an absorption maximum at 4000 A.U. Assum
