Abstract
THE atomization of molecular hydrogen at a hot tungsten surface has been studied extensively, some of the discussion being concerned with the correctness or otherwise of Langmuir's1 early work. Moore and Unterwald2 have summarized the various investigations up to 1964. In particular, it has often been stated that Langmuir's rates were βtoo low by factors which were all greater than 200β, the quoted assertion being first made by Bryce3 but often repeated since then (see for example refs. 3β6).
