Chapter 12, Problem 12.5QAP

Interpretation Introduction

Interpretation:

Thickness of nickel foil required for the transmission of 35.8 % power of incident beam

of Cu kα line needs to be calculated where 8.90g/cm³ is the density of nickel. And the mass absorption coefficient of nickel is 49.2 cm²/g measured by Cu kα line.

Concept introduction:

Beer’s law will be used for the calculation of thickness of Ni foil. This formula is given as-

$\ln \frac{P_o}{P}={\mu }_M\rho x$

Where,

P_o= transmitted beam power

P = incident beam power

µ_M = mass absorption coefficient

ρ = density

x = sample thickness
