Points from Foregoing Letters | Nature

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. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through
