StretchedKT

Description

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

A(t)=A_0\left(\frac{1}{3}+\frac{2}{3}\left(1-(\sigma t)^\beta\right)e^{-\frac{(\sigma t)^\beta}{\beta}}\right)

where,

\sigma is KuboToyabe decay rate,

A_0 is the amplitude,

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

Properties (fitting parameters)

Name Default Description
A0 1.0  
Beta 1.0  
Sigma 0.1
