New nuclide sup 263 Ha

A new nuclide {sup 263}Ha was produced in the bombardment of a {sup 249}Bk target with 93-MeV {sup 18}O ions. It was detected via spontaneous fission counting and was shown to have a half-life of about 0.5 min. This activity was also separated from the reaction products by automated rapid chemical s...

Zusammenfassung:	A new nuclide {sup 263}Ha was produced in the bombardment of a {sup 249}Bk target with 93-MeV {sup 18}O ions. It was detected via spontaneous fission counting and was shown to have a half-life of about 0.5 min. This activity was also separated from the reaction products by automated rapid chemical separations using cation-exchange chromatography in 0.05{ital M} {alpha}-hydroxyisobutyric acid. After chemical separation, {sup 263}Ha was found to decay by spontaneous fission (57{sub {minus}15}{sup +13}%) and by {alpha} emission ({ital E}{sub {alpha}}=8.35 MeV, 43%) with a half-life of 27{sub {minus}7}{sup +10} s. The spontaneous fission fragment energy spectrum is compatible with an average total kinetic energy of about 200 MeV.
