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.
