The Pb-208(n, gamma) cross section

Abstract

The Maxwellian average neutron capture (MAC) cross section of Pb-208 has been reinvestigated. With the activation technique cross section measurements were performed at 25, 30, 52, 104, 149, and 215keV. At 30keV we succceeded to measure the direct p-wave capture part of the Pb-208 capture cross section. The s-process at the termination of the synthesis has been analyzed. Independent calculations of s- and r-process yield a consistent decomposition for the Pb and Bi isotopic s- and r-contributions.
