Our group elected to re-evaluate the conclusions reached by a previous group regarding the mass of a J/Psi particle based on muon +/- and muon ++/-- decays.  The previous group concluded that the mass was either 3.05 GeV based on muon +- or 2.48 GeV based on muon ++/-- decay.  Our evaluation is attached:  http://www.i2u2.org/elab/cms/posters/display.jsp?name=adasf.data
