Abstract

We have investigated the (n,gamma) cross sections of p-process isotopes with the activation technique. The measurements were carried out at the Karlsruhe Van de Graaff accelerator using the Li-7(p, n) Be-7 source for simulating a Maxwellian neutron distribution of kT = 25 keV. Stellar cross section measurements are reported for the light p-process isotopes Pd-102, Te-120, Ba-130,Ba-132, and Dy-156. In a following paper the cross sections of Yb-168, W-180, Os-184, Pt-190, and Hg-196 will be discussed. The data are extrapolated to p-process energies by including information from evaluated nuclear data libraries. The results are compared to standard Hauser-Feshbach models frequently used in astrophysics.
