Talk:Quantum defect

n* = n - d.
Dear 129.67.134.65, sorry, I undid your revision. You put it in a wrong place and you did not write an expression for the quantum defect; could you please write such an expression (and recover your explanation) just below the indication of the second meaning of quantum defect? Will it be correct, to say that quantum dfect $$ d = n^* -n $$ ? Sincerely, dima 07:03, 23 July 2007 (UTC)
