“…One may note the neutron energies for this comparison, which are quite different from the usual value of 10 keV. These energies are taken from the earlier RIPL-1 compilation [24] except the case of more recent measurements [26,[36][37][38]. Nevertheless, these changes have no importance for the σ T (E) values around 1 MeV, which are of obvious importance for the competition between the neutron and chargedparticle decay of excited CN, in heavier Mo nuclei.…”

Background: The reliability of a previous α-particle optical-model potential (OMP) on nuclei with mass number 45≤A≤209 was proved for emitted α particles as well, for proton-induced reactions on Zn isotopes [Phys. Rev. C 91, 064611 (2015), Paper I]. However, the same was not the case of neutrons on Zr stable isotopes [Phys. Rev. C 96, 044610 (2017), Paper II].Purpose: A recent assessment of this potential also for nucleon-induced α-emission on A∼60 nuclei, including pickup direct reaction and eventual Giant Quadrupole Resonance (GQR) α-emission, is completed for neutrons incident on Zr, Nb, and Mo stable isotopes. Methods: Consistent sets of input parameters, determined through analysis of independent data, is involved while no further empirical rescaling factors of the γ and nucleon widths have been involved.Results: A suitable account of all competitive reaction channels is confirmed by careful uncertainty analysis, to avoid parameter ambiguities and/or error compensation. Additional validation of this potential is also supported by recently measured (α, γ) and (α, n) cross-sections of Zr and Mo nuclei.Conclusions: An increase of the α-emission beyond the statistical predictions, through consideration of additional reaction channels of the pickup direct interaction and like-GQR decay, makes possible the description of both absorption and emission of α particles by the same optical potential.

“…The thermal neutron capture-cross section of 100 Mo is σ c = 0.199 ± 0.003 b. For epithermal, intermediate, and resonance energy neutrons, there is an increased probability of interaction on 100 Mo, and the resonance integral cross-section ( I c ) of 100 Mo is approximately I c = 3.76 ± 0.15 b 54 – 56 . The epithermal to thermal neutron capture cross section ratio is ~18.8.…”

Technetium-101 (101Tc) has been poorly studied in comparison with other Tc isotopes, although it was first identified over ~80 years ago shortly after the discovery of the element Tc itself. Its workable half-life and array of production modes, i.e., light/heavy particle reactions, fission, fusion-evaporation, etc., allow it to be produced and isolated using an equally diverse selection of chemical separation pathways. The inherent nuclear properties of 101Tc make it important for research and applications related to radioanalytical tracer studies, as a fission signature, fusion materials, fission reactor fuels, and potentially as a radioisotope for nuclear medicine. In this review, an aggregation of the known literature concerning the chemical, nuclear, and physical properties of 101Tc and some its applications are presented. This work aims at providing an up-to-date and first-of-its-kind overview of 101Tc that could be of importance for further development of the fundamental and applied nuclear and radiochemistry of 101Tc.
