Theoretically derived masses in Mev; $Δ^{++}=1240.0, Δ^-=1243.4, Δ^0=1233.9, Δ^+=1232.6$. The first value differs considerably from the empirical value. Mass difference values are discussed.latex2e document; 8 pages Correction of $Δ^{++}$ mass calculation and revised discussionHigh Energy Physics - Phenomenologytext
