Chapter 18, Problem 49E

Interpretation Introduction

Interpretation:

The particle X which gives a nuclear fusion reaction with helium $-3$ nucleus to release an alpha particle and a positron is to be stated.

Concept introduction:

The elements whose nucleus decays spontaneously are known as radioactive elements. The decay is accompanied by the emission of alpha particles, beta particles, and gamma rays. All the elements which have an atomic number greater than $83$ are radioactive. In fusion reactions, a larger nucleus is formed by the combination of two small nuclei.
