    Notes: Abstract The off-shell reciprocal bootstrap model developed by Biswas and Balázs is used to calculate the mass and coupling-constant shifts of the nucleon andΔ-resonance in a self-consistent way. It is shown that the electromagnetic corrections to theΔNΠ coupling constant play a crucial role for obtaining the correct sign of the nucleon mass difference. The effects of mass splittings of exchanged and external particles are also included. The one-photon exchange contributions to the splittings of coupling constants and masses are calculated by means of the Frautschi-Dashen perturbation method. The result of the present calculation Mp−Mn= −1·8 MeV is in rough agreement with the experimental value −1·3 MeV.

    The self-consistency and electromagnetic properties of baryons (1966)
    Springer
    Czechoslovak journal of physics 16 (1966), S. 267-275

    Notes: Abstract The self-consistency condition is formulated in wave function formalism of quantum mechanics within the framework of the SU(3) group. Each member of the baryon octet is regarded as a bound state consisting of a baryon and a pseudoscalar meson. From this we derive the electromagnetic properties of baryons.
