Abstract: We have investigated the n,gamma cross sections of p-process isotopes withthe activation technique. The measurements were carried out at the KarlsruheVan de Graaff accelerator using the 7Lip,n7Be source for simulating aMaxwellian neutron distribution of kT = 25 keV. Stellar cross sectionmeasurements are reported for the light p-process isotopes 102Pd, 120Te,130,132Ba, and 156Dy. In a following paper the cross sections of 168Yb, 180W,184Os, 190Pt, and 196Hg will be discussed. The data are extrapolated top-process energies by including information from evaluated nuclear datalibraries. The results are compared to standard Hauser-Feshbach modelsfrequently used in astrophysics.
