Abstract
The new isotope 179Pb has been produced in the complete fusion reaction 40Ca + 144Sm → 179Pb+5n at the velocity filter SHIP (GSI). Its α-decay energy of 7350(20) keV and half-life value of 3.5+1.4- 0.8 ms were deduced based on the recoil-α-α correlation technique. A spin parity of I π = (9/2-) was tentatively assigned to the ground state of 179Pb; thus, it is based on the 1h9/2 orbital. Improved measurements of the α-decay properties of 179Tl m and 175Aum are also presented. © 2010 IOP Publishing Ltd.
