Abstract
FURTHER evidence for nuclear transformation by the capture of a K -electron from the extra-nuclear structure is provided by Wilson-cloud photographs, submitted by Dr. E. J. Williams and E. Pickup, of the photo-electrons produced by the K -characteristic radiation, the emission of which follows the removal of the K-electron. The striking feature is that, for the active nucleus concerned in these experiments, the capture of a K-electron appears to be at least 1000 times more probable than the emission of a positive electron, a process which would lead to the same final nucleus.
