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.
