Produces the non-relativistic Breit-Wigner probability density function for a particle of given width and mass_centre.

Parameters:¶

energy : sequence[float]¶

Energy domain over which the density is calculated.

mass_centre : float¶

Expected value of the mass peak for the particle.

width : float¶

The half-maximum-height width of the distribution, or simply the ‘width of the particle’.

Returns:¶

Densities corresponding to passed sequence of energy values.

Return type:¶

ndarray[float64]

Warns:¶

UserWarning – If the resolution of the passed energy data is lower than the width of the distribution.
