Abstract
A Q-value of -8.240-1 +/- 0.041 MeV has been determined for the exotic transfer reaction: Pt-198(O-18,F-17) Ir-199. This result yields a val ue of -24.425 +/- 0.041 MeV for the mass excess of the previously-unme asured nucleus, Ir-199. Excited states in this nucleus are indicated i n the region of 160 and 240 keV. The new result for the mass excess, t ogether with existing ones, has been used to investigate systematic tr ends in the n-p interaction strength across the Z = 82 and N = 126 she ll closures.
