Description

The new neutron-deficient isotope 208Th was produced in the complete-fusion reaction 64Ni+147Sm →208Th+3n. Evaporation residues were separated in-flight by the velocity filter SHIP and subsequently identified on the basis of energy-, position- and time-correlated α -decay chains. The measured α -decay energy and half-life value of 208Th are 8044(30)keV and 1.7+1.7-0.6 ms, respectively. Improved data on the α -decay of 209Th, 210Th, 212Th and 208Ra were obtained using complete-fusion reactions of 64Ni with 147Sm, 150Sm, and 152Sm targets. (orig.)
