Chapter 20, Problem 20.4QP

Interpretation Introduction

Interpretation: Electron and positron should be explained.

Concept Introduction:

${}_{\text{-1}}^{\text{0}}\text{β}$Particle- A beta particle can be a high energy, high speed, electron or a positron (electron with a positive charge).

The positron -- an antiparticle to the electron -- is much lighter, and has no known internal structure. It doesn't interact with nucleons via the strong force to my knowledge; and if it absorbs an electron, they both annihilate in an antimatter reaction, producing only light/photons.

To differentiate: Electron and positron
