Hydrogen spectroscopy

  1. Jun 26, 2010 #1
    I'm looking for the more precise value for the 2S-2P lamb shift transition frequency.
    I found the value 1 057 844.0(2.4) kHz in the National Institute of Standards and Technology website: http://physics.nist.gov/PhysRefData/HDEL/transfreq.html.
    Can someone tell me if there is a better value?

    I suspect that that is the best value known to date.
