Abstract
The fraction of capture to the 478 kev excited state of has been experimentally determined to be 0.107±0.02. The experimental method consisted in measuring the number of atoms by counting neutrons from the reaction, and in observing the subsequent number of 478 kev gammas by use of a counter calibrated by beta-gamma-coincidences from . Implications concerning the character of the 478 kev level are discussed.
