A comparative analysis of GEANT4, MCNP6 and FLUKA on proton‐induced gamma‐ray simulation

Medical Physics, Volume 52, Issue 6, Page 4862-4870, June 2025.
Abstract Background Precise range verification is essential in proton therapy to minimize treatment margins due to the steep dose fall‐off of proton beams. The emission of secondary radiation from nuclear reactions between incident particles and tissues stands out as a promising method for range verification. Two prominent techniques are PET and Prompt

On the impact of mass difference between the pions (π±-π0) and the nucleons (n-p) on the charge independence breaking of nuclear forces

Ядерна фізика та енергетика, 2017
Charge dependence of the pion-nucleon coupling constants and the 1S0-state low-energy nucleon-nucleon scattering parameters are studied on the basis of the Yukawa meson theory.

Experimental progress and status on nucleon electromagnetic form factors

EPJ Web of Conferences, 2016
Nucleon electromagnetic form factors are the fundamental quantities that are related to a two-dimensional view of the charge and magnetization distribution in the nucleon. They are essential in understanding the nucleon electromagnetic structure. In this

Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams

Medical Physics, Volume 52, Issue 6, Page 4924-4940, June 2025.
Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...

Neutron properties from light nuclei

EPJ Web of Conferences, 2017
We review the achievements of the project B.6. Topics addressed include pion photoproduction of three-nucleon systems, electromagnetic and axial currents in chiral nuclear EFT, aspects of EFTs with spin-3/2 fields, nuclear structure and dynamics from the

Genetic and morphological variation in the genus Zygogonium (Zygnematophyceae, Charophyta) from localities in Europe and North America and description of Z. angustum, sp. nov.

Journal of Phycology, Volume 61, Issue 3, Page 587-606, June 2025.
Abstract The globally distributed genus Zygogonium exhibits a narrow environmental range, with 19 morphologically described species. Its molecular characterization is poor, based on a single accession of the type species Z. ericetorum from Austria.

Peripheral nucleon-nucleon scattering at fifth order of chiral perturbation theory [PDF]

, 2014
We present the two- and three-pion exchange contributions to the nucleon-nucleon interaction which occur at next-to-next-to-next-to-next-to-leading order (N4LO, fifth order) of chiral effective field theory, and calculate nucleon-nucleon scattering in ...
