Measurement of the total muonium emission rate from silica aerogel using musr method
$\mu SR$
- magnetic field ~0.22 mT
- $\gamma_\mu = 0.13554 $ MHz/mT
- $\gamma_{Mu} = 14 $ MHz/mT
Principle of the method
muon once stopped in silica aerogel, forms ($65.5\pm1.8$)% muoniums and ($34.5\pm1.8$)% diamagnetic muons.
no muonium is stable in a metal. Thus, the precession spectrum gives us information on the timing distribution of the Mu reaching the foil.
Experimental method
RIKEN-RAL Muon Facility in ISIS, RAL
ARGUS $\mu SR$ spectrometer at RIKEN-RAL.
