Chapter 25.5, Problem 1RC

Interpretation Introduction

INTERPRETATION:

The particle which is seldom used as a bombarding particle to initiate the nuclear reaction should be determined from the given options.

CONCEPT INTRODUCTION:

Radioactive decay:

A nucleus undergoes disintegration in-order to become stable by emitting radiations such as alpha, beta and gamma particles.

Radioactive series:

The series in which successive disintegration of unstable nuclei is formed until a stable nucleus is formed.

Half life:

The time used for the decay of the half of the radioactive isotope to undergo decay.

$\text{Half}\text{life}\text{,}{\text{t}}_{\frac{\text{1}}{\text{2}}}\text{=}\frac{\text{0}\text{.693}}{\text{λ}}\text{where}\text{λ}\text{is}\text{the}\text{decay}\text{constant}$

Different types of projectiles used:

• Neutrons
• Alpha particle
• Protons
• Deuterons
