The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Gauge-Invariant Decomposition of Nucleon Spin [PDF]

, 1996
I introduce a gauge invariant decomposition of the nucleon spin into quark helicity, quark orbital, and gluon contributions. The total quark (and hence the quark orbital) contribution is shown to be measurable through virtual Compton scattering in a ...

Reconstructing the late Pleistocene glacial history of the Cairngorm Mountains, Scotland, using paired cosmogenic 10Be and 14C

Journal of Quaternary Science, EarlyView.
ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.

Influence of medium correction of nucleon nucleon cross section on the fragmentation and nucleon emission

, 2003
The influence of medium correction from an isospin dependent nucleon nucleon cross section on the fragmentation and nucleon emission in the intermediate energy heavy ion collisions was studied by using an isospin dependent quantum molecular dynamical ...

Three-Body Antikaon–Nucleon Systems [PDF]

, 2016
The paper contains a review of the exact or accurate results achieved in the field of the three-body antikaon–nucleon physics. Different states and processes in $$\bar{K}NN$$K¯NN and $$\bar{K}\bar{K}N$$K¯K¯N systems are considered.

Experimental validation of Geant4 nuclear interaction models in dose calculations of therapeutic carbon ion beams

Medical Physics, EarlyView.
Abstract Background The choice of nuclear interaction models in Monte Carlo simulations affects the dose calculation accuracy for light ion beam therapy. Purpose This study aimed to evaluate the dose calculation accuracy and simulation time of three GATE‐RTiON/Geant4 physics lists for therapeutic carbon ion beams, assessing their suitability for ...

Deconstructing 1S0 nucleon-nucleon scattering

, 2010
A distorted-wave method is used to analyse nucleon-nucleon scattering in the 1S0 channel. Effects of one-pion exchange are removed from the empirical phase shift to all orders by using a modified effective-range expansion.

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]

, 2016
We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

On the Nucleon-Nucleon Interaction

Physical Review, 1951
A charge-independent interaction between nucleons is assumed, which is characterized by a short range repulsion interior to an attractive well. It is shown that it is then possible to account for the qualitative features of currently known $n\ensuremath{-}p$ and $p\ensuremath{-}p$ scattering data. Some of the implications for saturation are discussed.
