LIGHT POLONIUM ISOTOPES FROM CARBON ION BOMBARDMENTS OF PLATINUM

HUGO ATTERLING, Wilhelm Forsling

Abstract

By bombarding platinum with C/sup 12/ and C/sup 13/ ions in the Stockholm 225-cm cyclotron, polonium isotopes of low mass numbers were produced and their alpha-decay properties studied. One of the alpha activities found was assigned to Po/sup 203/ with a particle energy of 5.48 Mev and a half-life of 45 plus or minus 10 minutes. For Po/sup 203/ a half life of 43 minutes was obtained. This is considerably shorter than reported earlier. (auth)
