Excitation function of (p, alpha) nuclear reaction on enriched 67Zn: Possibility of production of 64Cu at low energy cyclotron [PDF]

, 2014
The potential for production of the medically relevant 64Cu has been investigated by proton irradiation of highly enriched 67Zn targets. The excitation function of the 67Zn(p, α)64Cu a nuclear reaction was measured by the stacked-foil technique up to 30 ...

Study of (n,2n) reaction cross section of fission product based on neural network and decision tree models [PDF]

EPJ Web of Conferences
The neutron induced nuclear reaction cross sections of fission products are related with the neutron fiux and the reactor burnup, which are important for the accurate of nuclear engineering design. To predict the (n,2n) reaction cross section, especially

Validation of nuclear reaction models relevant to cosmic-ray neutron induced single-event effects in microelectronics

, 2011
The accuracy of nuclear reaction models used in the PHITS (Particle and Heavy Ion Transport code System) code, i.e., the INC model, the QMD model and the event generator mode (e-mode) with the evaluated nuclear data library JENDL-3.3 are validated to ...

Theoretical applications to nuclear astrophysics [PDF]

EPJ Web of Conferences
Nuclear reaction study is important to understand elemental abundance in the universe and stability of stars. For several reactions due to the paucity of experimental data or diffculties in performing the direct measurements, we depend upon theoretical ...

Measurement of (n, xnγ) reaction Cross-sections on natural lead using in-beam gamma-Ray spectroscopy [PDF]

Nuclear Technology and Radiation Protection, 2003
New concepts in nuclear reactor technology require precise neutron reaction data in the intermediate and high energy range. At present, experimental and evaluated nuclear data, particularly for (n, xn) reactions, are very scarce.

Interpretation of the Optical Model in Nuclear Reactions [PDF]

Progress of Theoretical Physics, 1959
The theoretical basis of the nuclear optical model is investigated for the elastic scattering of neutrons at low energies. It is argued in connection with statistical mechanics of irreversible processes that the characteristic feature of the optical model can be revealed by means of wave packets whose energy spread is wide enough to cover many compound

Critical review of CIELO evaluations of n+ 235U, 238U using differential experiments

EPJ Nuclear Sciences & Technologies, 2018
Key reactions have been selected to compare JEFF-3.3 (CIELO 2) and IAEA CIELO (CIELO 1) evaluated nuclear data files for neutron induced reactions on 235U and 238U targets. IAEA CIELO evaluation uses reaction models to construct the evaluation prior, but
