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…
