Real‐time energy measurement of clinical carbon ion beams using a cross‐correlation time‐of‐flight method with parallel‐plate chambers [PDF]

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background In carbon‐ion radiotherapy (CIRT), the beam energy determines both the particle range and the overall dosimetric quality. Range‐verification QA devices such as Zebra and Giraffe, which are based on multilayer ionization chambers (MLICs), can verify the range but only under dedicated QA conditions, leaving any energy deviations ...

An optimized chiral nucleon-nucleon interaction at next-to-next-to-leading order [PDF]

, 2013
We optimize the nucleon-nucleon interaction from chiral effective field theory at next-to-next- to-leading order. The resulting new chiral force NNLOopt yields \chi^2 \approx 1 per degree of freedom for laboratory energies below approximately 125 MeV. In

Chromo-Electric Field Energy in Quark Models

Frontiers in Physics, 2019
We study the contribution of the chromo-electric field to the total energy of the hadrons. We analyze the case of quarks considered as extended sources of the field. Specific forms of the interaction potential of the quarks are obtained.

Elliptic flow in heavy ion collisions near the balance energy [PDF]

, 1999
The proton elliptic flow in collisions of Ca on Ca at energies from 30 to 100 MeV/nucleon is studied in an isospin-dependent transport model. With increasing incident energy, the elliptic flow shows a transition from positive to negative flow.

New Laser Fusion and Its Gain by Intense Laser

Energies, 2010
The feasibility of a new approach of laser fusion in plasma without implosion has been proposed and is discussed using an intense laser. The cross section of the nuclear reaction is increased by enhancing the penetrability of nuclei through the Coulomb ...

Quark Models of the Nucleon–Nucleon Interaction

Frontiers in Physics, 2020
The present paper aims to provide a review of the relevance of quark degrees of freedom in the description of the nucleon-nucleon and, in general, of the baryon-baryon interaction.

Analyzing power in nucleon-deuteron scattering and three-nucleon forces [PDF]

, 1999
Three-nucleon forces have been considered to be one possibility to resolve the well known discrepancy between experimental values and theoretical calculations of the nucleon analyzing power in low energy nucleon-deuteron scattering.

Low-energy neutron-deuteron reactions with N3LO chiral forces [PDF]

, 2014
We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-to-leading order in the chiral expansion.

Realistic Model of the Nucleon Spectral Function in Few- and Many- Nucleon Systems [PDF]

, 1995
By analysing the high momentum features of the nucleon momentum distribution in light and complex nuclei, it is argued that the basic two-nucleon configurations generating the structure of the nucleon Spectral Function at high values of the nucleon ...
