Chapter 24, Problem 24.130P

(a)

Interpretation Introduction

Interpretation:

Energy and wavelength of gamma ray that would convert excited state I to ground state has to be determined.

Concept Introduction:

In the radioactive decay process the unstable isotopes loses their energy by emitting radiation in order to attain stable species. It is converted in to stable isotopes by emitting positron ${}_{+1}^0\beta$ , gamma ${}_0^0\gamma$ , Beta $\beta$, alpha ${}_2^{4}He$ and or by electron capture ${}_{-1}^{0}e$ .

Planck’s equation,

  $\begin{array}{c}\text{E}\text{=}\text{hν}\text{=}\frac{\text{hc}}{\text{λ}}\\ \text{where, ν}=\text{frequency}\\ \text{λ}=\text{wavelength}\end{array}$

The energy increases as the wavelength of the light decreases.

(b)

Interpretation:

Energy of the $\alpha$ particle that would raise ${}^{233}U$ to excited state II has to be determined.
