摘要：
The present measurements were performed by means of the activation technique. Neutrons were produced at the Karlsruhe Van de Graaff accelerator via the Li-7(p,n)Be-7 reaction. For proton energies just above threshold, one obtains a neutron spectrum similar to a Maxwellian distribution for kT = 25 keV. This quasi-stellar neutron spectrum allowed us to measure the Maxwellian, averaged cross sections directly. The experimental results of Yb-174,Yb-176, W-184,W-186, Os-190,Os-192 Pt-196,Pt-198, and Hg-202 were extrapolated from kT = 25 keV to lower and higher temperatures.
