Talk:Isotopic shift

Dear author and readers,

thank you for this article.

While looking for a copy of the reference

" 2 ^ W. Pauli, R. E. Peierls, Phys. Z. 32 (1931) 670 "

I found that the reference is not correct. In "Phys. Z 32, 1931, pp. 670-674" is an article by Estermann, I; Frisch, R; Stern, O

One possibly should find the correct citation or delete the quotation.

Best wishes,
