Chapter 14, Problem 14.96PAE

Interpretation Introduction

Interpretation:

The N/Z ratios for ¹⁹²Ir and ¹³⁷Cs should be compared with N/Z ratio of their nearest stable isotopes.

Concept introduction:

The N/Z ratio is defined as the ratio of number of neutron and atomic number of radioactive nuclei.

For example,

For ¹⁹²Ir, the value of N=115 and Z=77

Thus, the N/Z ratio will be 1.493.
