Help, Need a reference web site

    I'm in the middle of writing up the Frank-Hertz experiment as part of my lab module this year, but I'm having trouble finding a 'reliable' web site that I can use to quote the electron energy value (ie 4.9eV).

    I'm afraid my lecturer refuses to acknowledge wikipedia as a good source.

    So, even though I have the value that I need, could anyone suggest a website that I can use as a source for this info - and therefore for future work.
