${{\boldsymbol \mu}}$ MASS INSPIRE search

2010 CODATA (MOHR 2012 ) gives the conversion factor from u (atomic mass units, see the above datablock) to MeV as 931.494$~061~$(21). Earlier values use the then-current conversion factor. The conversion error contributes significantly to the uncertainty of the masses given below.

1  Converted to MeV using the 1998 CODATA value of the conversion constant, $931.494013$ $\pm0.000037$ MeV/u.
2  MARIAM 1982 give ${\mathit m}_{{{\mathit \mu}}}/{\mathit m}_{{{\mathit e}}}$ = 206.768259(62).
3  CROWE 1972 give ${\mathit m}_{{{\mathit \mu}}}/{\mathit m}_{{{\mathit e}}}$ = 206.7682(5).
4  CRANE 1971 give ${\mathit m}_{{{\mathit \mu}}}/{\mathit m}_{{{\mathit e}}}$ = 206.76878(85).
