Times Cited Count:43 Percentile:90.03(Physics, Nuclear)Cross sections of the W, Re, Os() reactions were measured using quasi-monochromatic photon beams from laser Compton scattering (LCS) with average energies from 7.3 to 10.9 MeV. The results are compared with the predictions of Hauser-Feshbach statistical calculations using four different sets of input parameters. In addition, the inverse neutron capture cross sections were evaluated by constraining the model parameters, especially the strength function, on the basis of the experimental data. The present experiment helps to further constrain the correction factor for the neutron capture on the 9.75 keV state in Os. Implications of to the Re-Os cosmochronology are discussed with a focus on the uncertainty in the estimate of the age of the Galaxy.

Photodisintegration experiments were carried out for W, Re, and Os using quasi-monochromatic -ray beams from laser Compton scattering (LCS) at the National Institute of Advanced Industrial Science and Technology. The excitation function of (,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 W, Re, and 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.

Times Cited Count:35 Percentile:84.6(Physics, Nuclear)The neutron capture cross section of the unstable s-process branching nucleus W has been derived from experimental data of the inverse W(,n)W photodisintegration taken with monochromatic photon beams from laser Compton scattering. The result of mb at keV leads to a relatively high effective neutron density in the classical s process of . A realistic model for the s process in thermally pulsing AGB stars overestimates the abundance of Os significantly because of the relatively small neutron capture cross section of W.
