Abstract
K. J. Bostrom, J. Koch and T. Lauritsen have found short periods for the delayed neutron emission accompanying uranium fission in addition to the two previously known periods of 12 seconds and 45 seconds. The results can be related with the measurements on short β-ray periods from uranium fission, and can be explained by theoretical considerations recently published by Bohr and Wheeler.
