Abstract
Bombardment of targets with 80- to 140-Mev ions has resulted in the identification of a new alpha activity decaying with a half-life of 4.3±0.2 min and an alpha-particle energy of 3.99±0.03 Mev. Subsequent experiments have established that the activity is due to an isomeric state of . It is proposed that the isomerism due to the filling of an proton state for the spherical Tb isotopes.
