Using 230 million B{bar B} events recorded with the BABAR detector at the e{sup +}e{sup -} storage rings PEP-II, they reconstruct approximately 4100 B{sup 0} {yields} J/{psi} K{sup +}{pi}{sup -} and 9930 B{sup +} {yields} J/{psi}K{sup +} decays with J/{psi} {yields} {mu}{sup +}{mu}{sup -} and e{sup +} e{sup -}. From the measured B-momentum distributions in the e{sup +}e{sup -} rest frame, they determine the mass difference m(B{sup 0}) - m(B{sup +}) = (+0.33 {+-} 0.05 {+-} 0.03) MeV/c{sup 2}.
