Activation cross sections for 190Os(n,p)190m,gRe, 188Os(n,p)188Re and 190Os(n,n′)190mOs reactions from 13.5 to 14.8 MeV
چکیده انگلیسی

Cross sections for (n,p) and (n,n′) reactions have been measured on osmium isotopes at the neutron energies from 13.5 to 14.8 MeV using the activation technique in combination with high-resolution gamma-ray spectroscopy. Neutrons were produced via the 3H(d,n)4He reaction using solid TiT. The neutron fluences were determined using the monitor reaction 93Nb(n,2n)92mNb. Data are reported for the following reactions: 190Os(n,p)190mRe, 190Os(n,p)190gRe, 190Os(n,p)190Re, 188Os(n,p)188Re and 190Os(n,n′)190mOs. Nuclear model calculations using the code HFTT, which employs the Hauser–Feshbach (statistical model) and exciton model (precompound effects) formalisms, were undertaken to describe the formation of the products. The cross sections were discussed and compared with experimental data found in the literature, with values of model calculations including the pre-equilibrium contribution, and with evaluation data of JEFF-3.1/A.
