Photo-carrier generation with 420 nm light (hv=2.95 eV) in an anthracene single crystal has been studied, The main experimental results are the following: ( 1) The photocurrent waveforms correspond to the penetration depth of the exciting light. (2) The number of carriers generated is proportional t

The rate of diffusion of antimony in copper single crystals has been measured over the temperature range 600'1OOO'C by means of a sectioning technique employing the Sblz4 radio-isotope as tracer. The diffusion activation eneigy and frequency factor were found to be 42000 & 700 cal mole-l and 0.34 5
