Multiple Scattering Angle

[math]\theta_{0} = \frac{13.6 MeV}{\beta cp}z{\sqrt{x/X_{0}}}{[1+0.038ln{(x/X_{0})}]}[/math]

p = momentum of the incident particle

[math]\beta[/math]c = velocity of the incident particle

z = charge number of the incident particle

[math]x/X_{0}[/math] = thickness of the scattering medium in radiation lengths
