| Popis: | The new isotope 179Pb has been produced in the complete fusion reaction 40Ca+144Sm->179Pb+5n at the velocity filter SHIP (GSI). Its alpha-decay energy of 7350(20) keV and half-life value 3.5 (+1.4/-0.8) ms were deduced based on the recoil-alpha-alpha correlation technique. A spin parity of I=(9/2-) was tentatively assigned to the ground state of 179Pb; thus, it is based on the 1h9/2 orbital. Improved measurements of the alpha-decay properties of 179Tlm and 175Aum are also presented. ispartof: Journal of Physics G, Nuclear and Particle Physics vol:37 issue:3 status: published |
