Quick question about notation for normalisation

  1. Feb 5, 2012 #1
    Just a quick question, I'm looking to express the normalisation condition formally mathematically, is this acceptable:

    [itex]1=\int_R|\psi|^2 \ \mathrm{d}\tau[/itex]

    For a particle in 3 dimensional region R.

    Tau is rarely used to denote a volume integral, I think V or d^3r is a lot more standard. Tau is usually reserved for the proper time (or some characteristic time).

    I think I've been using a textbook from about 18 years ago, so this could explain why. Thank you. (:
