Carbon Elastic and Inelastic Stopping-Power Components for Heavy Ions at Bohr and Higher Velocities
Atoms, 2023 Carbon stopping power (SP) data for heavy ions (HIs), obtained around Bohr velocities, revealed remarkably lower values than those predicted using the SRIM/TRIM calculations/simulations.

Forbidden nuclear reactions [PDF]
Physical Review C, 2019 Exothermal nuclear reactions which become forbidden due to Coulomb repulsion in the\ $\varepsilon \rightarrow 0$ limit ($\lim_{\varepsilon \rightarrow 0}σ\left( \varepsilon \right) =0$) are investigated. ($σ\left( \varepsilon \right) $ is the cross section and $\varepsilon $ is the center of mass energy.) It is found that any perturbation may mix ...

Metallic Nanoparticles: A Useful Prompt Gamma Emitter for Range Monitoring in Proton Therapy?
Radiation, 2021 In clinical practice, dose delivery in proton therapy treatment is affected by uncertainties related to the range of the beam in the patient, which requires medical physicists to introduce safety margins on the penetration depth of the beam.

Interphase Surface Stability in Liquid-Liquid Membrane Contactors Based on Track-Etched Membranes
Membranes, 2021 A promising solution for the implementation of extraction processes is liquid–liquid membrane contactors. The transfer of the target component from one immiscible liquid to another is carried out inside membrane pores.

Transfer Reactions in Nuclear Astrophysics [PDF]
EPJ Web of Conferences, 2023 Transfer reactions are important tool in nuclear astrophysics. These reactions allow us to identify states in nuclei and to find the corresponding energies, to determine if these states can contribute to astrophysical nuclear reactions and ultimately to ...

Nuclear Structure and Simple Nuclear Reactions [PDF]
Physical Review, 1960 Recently it has become increasingly evident that some assumptions in the nuclear model used for the Monte Carlo calculations yield cross section values which are not in accord with experiment. In particular, calculations of ($p, \mathrm{pn}$)-reaction cross sections in the Bev energy range give values which are low by factors of two to nine when ...

Direct reactions for nuclear astrophysics [PDF]
EPJ Web of Conferences, 2023 The neutron activation technique is a well established method to measure neutron capture cross sections relevant for the s-process. The 7Li(p,n) reaction at Ep = 1912 keV is often used as a neutron source since the energy distribution of the emitted ...
