.. index:: MuMinusExpTF

Description

A relatxation function for negative muons in Traverse field.

N(t)=N_0e^{-frac{t}{\tau}}\left(1+Ae^{-\lambda t}\cos(2\pi\nu t + \phi)\right)

where,

N_O is the count at t=0 ,

\tau is the muon decay life time,

A is the relative amplitude of the oscillatory term,

\lambda (MHz) is the relaxation rateo f the oscillatory term,

\nu is the oscillating frequency,

and \phi is the phase.
