Bethe stopping-power theory for heavy-target atoms

Bethe stopping-power theory for heavy-target atoms.

Stopping Power Calculations for Heavy Relativistic Ions

Recent theoretical results have led to improvements in formulas for dE=dx, particularly in the regime of high projectile charge and moderate to highly relativistic velocities. In addition, integration of dE=dx leads to predictions of total range given initial energy and, reciprocally, initial energy given total range. We have compiled theoretical formulas for dE=dx from a variety of sources int...

Heavy Quark Effective Theory, Interpolating Fields and Bethe-Salpeter Amplitudes1

We use the LSZ reduction theorem and interpolating fields, alongwith the heavy quark effective theory, to investigate the structure of the BetheSalpeter amplitude for heavy hadrons. We show how a simple form of this amplitude, used extensively in heavy hadron decay calculations, follows naturally upto O(1/M) from these field theoretic considerations.

SLPI: a new target for stopping metastasis

Resonant charging and stopping power of slow channelling atoms in a crystalline metal

Fast moving ions travel great distances along channels between low-index crystallographic planes, slowing through collisions with electrons, until finally they hit a host atom initiating a cascade of atomic displacements. Statistical penetration ranges of incident particles are reliably used in ion-implantation technologies, but a full, necessarily quantum-mechanical, description of the stoppin...
