“…P α tr is the α transmission probability from inside to outside the nucleus, which is given by the unit step function at the Coulomb potential at a distance of r 0 + 1.5 fm from the center of the target nucleus. P α def is the α deflection [30] at the nuclear surface when the α particle leaves the nucleus:…”

“…Indirect pickup is considered to be a final-state interaction and is known to be responsible for the low-energy part of the spectra of proton-nucleus reactions above a few hundred megaelectronvolts. This process is included in the present 0 10 20 30 model, and its implementation is described in Ref. [26].…”

“…According to Eq. ( 14), a nucleon that has sufficient kinetic energy to 0 10 20 30 leave the nucleus after any interactions is able to pick up other nucleons at the exit. The calculation algorithm of this process is similar to, but simpler than, that of the coalescence method employed by molecular-dynamics models [32,33] and other INC models [34,35].…”

Inclusive (p, αx) reactions from 42 to 300 MeV are investigated to quantitatively understand the roles of direct pickup and knockout processes. These two processes as well as indirect pickup are incorporated into the intranuclear cascade model. Calculations followed by the evaporation model successfully explain the double-differential cross-section spectra in terms of both shape and magnitude. Direct pickup occupies the low excitation energies of the spectra, and knockout appears between the direct pickup and evaporation regions. The contribution of knockout is negligible below 100 MeV, increases to be comparable with that of direct pickup at 160 MeV, and is dominant above 200 MeV. Indirect pickup shows an important contribution at 300 MeV. The direct pickup and knockout processes show decreasing trends of incident-energy dependence, common to targets ranging from 12 C to 209 Bi. However, the decrease of direct pickup is much faster than that for knockout.

“…Given the advantages of economic efficiency and safety, numerous studies have employed ion irradiation as a means of simulating the neutron irradiation process, thereby facilitating the observation of comparable radiation phenomena. [14][15]. The experimental approach involves conducting transmission electron microscope (TEM) examinations and nanoindentation measurements to characterize the microstructural evolution and hardness changes.…”

The irradiation-induced hardening behavior of Zircaloy-2 under irradiation with 3.2 MeV Ni 3+ ions at room temperature (RT) with stress conditions was investigated using transmission electron microscope (TEM) examination and nanoindentation measurements. The results indicated that the impact of external tensile stress on the hardening of unirradiated samples was not significant. Although stress-induced dislocation lines were observed in samples stressed above 450 MPa, they were unevenly distributed and not dense enough to cause significant changes in hardness. Samples subjected to 1 dpa irradiation under stress exhibited a noticeable increase in hardness, but the extent of hardening remained nearly unchanged across different stress levels, suggesting a minor influence of external tensile stress. This study offers insights into the irradiation-induced hardening behavior of Zircaloy-2 subjected to a 1 dpa irradiation under the influence of external stress conditions at room temperature.
