StretchedKT

Description

For observation of muon spin relaxation MuSR spectra with lineshapes lying between a Guassian and a Lorentzian,

A(t)=A0(13+23(1(σt)β)e(σt)ββ)

where,

σ is KuboToyabe decay rate,

A0 is the amplitude,

β is the stretching exponential and it ranges from 1 (neglible nuclear field) and 2 (strong nuclear field).
