Alpha decay studies of new neutron-deficient francium isotopes and their daughters

Neutron-deficient francium isotopes were produced by proton-induced spallation reactions and investigated by alpha spectroscopy following on-line mass separation. The new isotopes /sup 202,202/Fr were identified and their half-lives measured. An improved value for the half-life of /sup 203/Fr was ob...

description Neutron-deficient francium isotopes were produced by proton-induced spallation reactions and investigated by alpha spectroscopy following on-line mass separation. The new isotopes /sup 202,202/Fr were identified and their half-lives measured. An improved value for the half-life of /sup 203/Fr was obtained. Alpha branching ratios were determined for /sup 198m, g,199/At. The derivation of the mass excess of /sup 202/Fr and the systematics of alpha energies and reduced widths are discussed. (17 refs).
