Abstract

The production cross sections of four $N = 127$ isotones ( $^{207}$ Hg, $^{206}$ Au, $^{205}$ Pt, and $^{204}$ Ir) have been measured using ( $p$ , $n$ ) charge-exchange reactions, induced in collisions of a $^{208}$ Pb primary beam at 1 A GeV with a Be target. These data allow one to investigate the use of a reaction mechanism to extend the limits of the chart of nuclides toward the important $r$ -process nuclei in the region of the third peak of elemental abundance distribution.
