The pattern of the isospin splittings is not spoiled by the terms of the order $O(\ms \dm)$, and both splittings between the different isospin multiplets and within the same multiplet are well reproduced for acceptable values of $\ms$ and $\dm$.11 pages, RUB-TPII-6/94High Energy Physics - Phenomenologytext
