Coupled-channels calculations for nuclear reactions: from exotic nuclei to superheavy elements [PDF]
, 2022 Atomic nuclei are composite systems, and they may be dynamically excited during nuclear reactions. Such excitations are not only relevant to inelastic scattering but they also affect other reaction processes such as elastic scattering and fusion. The coupled-channels approach is a framework which can describe these reaction processes in a unified ...

Molecules, 2011 The conventional reaction yield evaluation for radioisotope production is not sufficient to set up the optimal conditions for producing radionuclide products of the desired radiochemical quality. Alternatively, the specific radioactivity (SA) assessment,

Ab Initio Nuclear Reaction Theory with Applications to Astrophysics [PDF]
arXiv, 2022 We present an introduction to ab initio nuclear theory with a focus on nuclear reactions. After a high-level overview of ab initio approaches in nuclear physics, we give a more detailed description of the no-core shell model technique equivalent to a large extent to configuration-interaction methods applied in quantum chemistry.

TDHF and a macroscopic aspect of low-energy nuclear reactions [PDF]
, 2020 Time-dependent Hartree--Fock (TDHF) method has been applied to various low-energy nuclear reactions, such as fusion, fission, and multinucleon transfer reactions. In this Mini Review, we summarize recent attempts to bridge a microscopic nuclear reaction theory, TDHF, and a macroscopic aspect of nuclear reactions through nucleus--nucleus potentials and ...

Measurement of alpha-induced reaction cross-sections for $^{nat}$Zn with detailed covariance analysis [PDF]
, 2022 The production cross-section of $^{68}$Ge, $^{69}$Ge, $^{65}$Zn and $^{67}$Ga radioisotopes from alpha-induced nuclear reaction with $^{nat}$Zn have been measured using the stacked foil activation technique followed by the off-line $\gamma$-ray spectroscopy in the incident alpha energy range 14-37 MeV.

Soft Dipole Resonances in 8He and 8C [PDF]
EPJ Web of ConferencesSoft dipole resonances in 8He and 8C are investigated by applying the complex scaling method to the α + N + N + N + N five-body model for the isospin T = 2 system.

Uses of alpha particles, especially in nuclear reaction studies and medical radionuclide production
, 2016 Alpha particles exhibit three important characteristics: scattering, ionisation and activation. This article briefly discusses those properties and outlines their major applications. Among others, α-particles are used in elemental analysis, investigation

Reinvestigating the Gamow Factor of Reactions on Light Nuclei
The Astrophysical Journal, 2023 We present a modified Gamow factor by reinvestigating the conventional assumptions used in its derivation. The conventional Gamow factor, factorized from the total cross section, effectively describes the penetration probabilities (PPs) in low-energy ...
