Photoneutron cross section measurements on $$^{186}$$W, $$^{187}$$Re and $$^{188}$$Os for cosmochronology

Photodisintegration experiments were carried out for $$^{186}$$W, $$^{187}$$Re, and $$^{188}$$Os using quasi-monochromatic $$gamma$$-ray beams from laser Compton scattering (LCS) at the National Institute of Advanced Industrial Science and Technology. The excitation function of ($$gamma$$,n) cross sections was measured for the three nuclei near neutron thresholds, taking advantage of the intense peaking of the energy-tunable LCS beam in the energy region of astrophysical importance. Neutron capture cross sections for $$^{185}$$W, $$^{186}$$Re, and $$^{187}$$Os are evaluated from the photodisintegration data with the Hauser-Feshbach statistical model. We quantitatively discuss the two corrections factors for the s-process branchings and the neutron capture on the 9.75 keV state.

With using $$^{17}F$$ RNB from CRIB, proton inelastic scattering was observed. From this experiment, some resonance parameters have been deduced for the key reaction, $$^{14}O(alpha,p)^{17}F$$ at the explosive hydrogen burning stage in stars. Proton inelastic scattering of $$^{23}Mg$$ are also reported.
