satlas.utilities.utilities.beta(mass, V)[source]¶

Calculates the beta-factor for a mass in amu and applied voltage in Volt. The formula used is

$\beta = \sqrt{1-\frac{m^2c^4}{\left(mc^2+eV\right)^2}}$

Parameters:	mass (float) – Mass in amu. V (float) – voltage in volt.
Returns:	Relativistic beta-factor.
Return type:	float
