MuMinusExpTF

Description

A relatxation function for negative muons in Traverse field.

N(t)=N0efractτ(1+Aeλtcos(2πνt+ϕ))

where,

NO is the count at t=0 ,

τ is the muon decay life time,

A is the relative amplitude of the oscillatory term,

λ (MHz) is the relaxation rateo f the oscillatory term,

ν is the oscillating frequency,

and ϕ is the phase.
