In the previous section, the Lorentzian theory was introduced as a muon spin relaxation theory for dilute spin systems.
Still, a truly Lorentzian distribution is unphysical, because some fraction of the muons must locate at an infinitesimally small distance from a magnetic ion, in order to realize the diverging second moment of the Lorentzian distribution
In the traditional Lorentzian theory, the relaxation function in this regime is a square-root exponential function (eq.
spectroscopy), I need to decompose the original curve into three fitting curves, and I want to define my own fitting method for the peak type, which is mostly used in the XPS analysis software, its a mixture of a Gaussian and a Lorentzian, and I can change the ratio of the two in the method.

in PsdViogt1, Gaussian and Lorentzian have the same width
