# On a Positron Channeling in Ionic Crystals

## TL;DR

This paper derives an analytical potential for fast charged particles in CsCl crystals and explores the feasibility of positron channeling along the <100> axis, showing temperature independence of the potential.

## Contribution

It provides a new analytical expression for the effective interaction potential of positrons in ionic crystals near the <100> axis.

## Key findings

- Positron channeling is possible in CsCl crystals.
- The effective potential is nearly temperature-independent.
- Numerical analysis supports the feasibility of positron channeling.

## Abstract

An analytical expression is received for the effective interaction potential of a fast charged particle with the ionic crystal CsCl near the direction of axis <100> as a function of the temperature of the medium. A possibility of positron channeling in this potential is shown. By numerical analysis it is shown that the effective potential of axial channeling of positrons along the axis <100> of negatively charged ions practically does not depend on temperature of the media.
