hazma.decay.muon(eng_gam, eng_mu)¶

Compute dNdE from muon decay.

Compute dNdE from decay \(\mu^{\pm} \to e^{\pm} + \nu_{e} +\nu_{\mu} + \gamma\) in the laborartory frame given a gamma ray engergy of eng_gam and muon energy of eng_mu.

Parameters:	eng_gam (numpy.ndarray) – Gamma ray energy(ies) in laboratory frame. eng_mu (double) – Muon energy in laboratory frame.
Returns:	spec (numpy.ndarray) – List of gamma ray spectrum values, dNdE, evaluated at eng_gam given muon energy eng_mu.

Examples

Calculate spectrum for single gamma ray energy

>>> from hazma import decay
>>> eng_gam, eng_mu = 200., 1000.
>>> spec = decay.muon(eng_gam, eng_mu)

Calculate spectrum for array of gamma ray energies

>>> from hazma import decay
>>> import numpy as np
>>> eng_gams = np.logspace(0.0, 3.0, num=200, dtype=float)
>>> eng_mu = 1000.
>>> spec = decay.muon(eng_gams, eng_mu)
