THE WORK FUNCTION OF THORIUM
Journal Article

· Proc. Phys. Soc. (London)
The average work functions of vacuum-deposited thorium films and of thorium foil were measured by the Kelvin contact-potential-difference method, under ultra-high vacuum conditions. A reproducible value of 3.455 plus or minus 0.012 ev was found for the work functron of the vacuum-deposited films. In the case of the foil, the work function increased continuously with the duration of electron bombardment, eventually reaching a limitlng value of 3.728 plus or minus 0.010 ev after ninety-seven hours of bombardment. Reasons were discussed for identrfying this value with the average work function of well-aged, polycry stalline thorium. (auth)
