Stellar (n,γ) cross sections of p-process isotopes Part I: ¹⁰²Pd, ¹²⁰Te, ¹³⁰̓¹³²Ba, and ¹⁵⁶Dy

We have investigated the (n,γ) cross sections of p-process isotopes with the activation technique. The measurements were carried out at the Karlsruhe Van de Graaff accelerator using the 7 Li(p, n) 7 Be source for simulating a Maxwellian neutron distribution of kT = 25 keV. Stellar cross section measurements are reported for the light p-process isotopes 102 Pd, 120 Te, 130,132 Ba, and 156 Dy. In a following paper the cross sections of 168 Yb, 180 W, 184 Os, 190 Pt, and 196 Hg 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.
