Muonium-style Decoupling Curve¶
Description¶
A Muonium-style decoupling curve is defined as:
where
\(A_R\) - the repolarising asymmetry
\(B_0\) - the decoupling field
\(A_\mathrm{BG}\) - the background asymmetry
The function models the repolarisation of isotropic muonium. The x axis should be the magnetic field, typically scanned from 0 to a few kGauss. The y axis is the asymmetry.
Examples¶
This has been used in examining the influence of strong magnetic field on the depolarizations of Muons[1] and in investigating the Paschen-Back Effect as a means of detecting Muonium[2].
