Times Cited Count：2 Percentile：20.93(Nuclear Science & Technology)Toward the development of the next version of Japanese Evaluated Nuclear Data Library (JENDL) general-purpose file, we calculate neutron cross-sections on 
Cu from 50 keV to 20MeV, which is the incident energy range above the resolved resonance region in JENDL-4.0. A dispersive optical model potential is adopted with a coupled-channel method for interaction between neutron and 
Cu. Direct, pre-equilibrium, and compound processes are taken into account in the calculation. All cross-sections, differential and double-differential cross-sections are consistently calculated with a single set of model parameters. The calculation results reproduce the measured data very well. In addition, disagreement between the calculated and experimental values seen in an integral test for the 
Cu
reaction is improved by using the cross-section data obtained from the present work.

Times Cited Count：44 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.
