Talk:Breit equation

the Breit 'equation' isn't so much of an equation as it is just a perturbing operator. Also, in the literature it is usually called the Breit-Pauli operator. I think the title of the article should reflect that.

Question. For H6, is it assumed that the vector potential A is in the Coulomb gauge? Also, p needs to be defined. Xxanthippe (talk) 23:26, 4 December 2009 (UTC).

Index in H3?
There seems to be a free index j in the H3 term. The first term consists of the inner product of spin s_i with the outer product [F(r_ij) x p_i]. In my opinion, the index j in F(r_ij) is not correct since there is no summation or other reference to it.129.13.72.198 (talk) 11:38, 21 February 2012 (UTC)

Typo in Equation for H_6 ?
It seems to me that there is mistake in the equation giving H_6. The factor mu_B should be inside the parenthesis (just before H) as it concerns only the spin contribution, not the orbital one. Can anyone confirm this? — Preceding unsigned comment added by 160.103.208.60 (talk) 15:30, 19 August 2019 (UTC)
