The neutron capture cross section of the unstable s-process branching nucleus $$^{185}$$W has been derived from experimental data of the inverse $$^{186}$$W($$gamma$$,n)$$^{185}$$W photodisintegration taken with monochromatic photon beams from laser Compton scattering. The result of $$sigma = 553 pm 60$$mb at $$kT = 30$$keV leads to a relatively high effective neutron density in the classical s process of $$N_{rm{n}} = 4.7 times 10^8,{rm{cm}}^{-3}$$. A realistic model for the s process in thermally pulsing AGB stars overestimates the abundance of $$^{186}$$Os significantly because of the relatively small neutron capture cross section of $$^{185}$$W.

Measurement of neutron capture cross sections of Tc-99

For studies on incineration of long-lived fission products (LLFPs) in a fast reactor, detailed characteristics of reactor core such as incineration performance have to be investigated. Therefore, accurate neutron cross section data of LLFPs become necessary. In the present study, in order to perform the precise measurements of keV-neutron capture cross sections of Tc-99, which is one of most important LLFPs, the details of the Tc-99 sample and the measurements with our experimental facilities were investigated.
