PROF. C. G. BARKLA ON X-RAYS AND THE THEORY OF RADIATION. 
345 
and this should be compared with the theoretical value —-. The values in 
n+n L 
Table V. should in this case be multiplied by 
n + n L 
n 
to give the number of quanta of 
K radiation emitted per K electron ejected. They then become 1 ’22, 1‘04, 0‘92, 0‘86, 
and 0'94.
