Ein klassisches Teilchenmodell mit variablem Gravitationskoeffizienter
The unified theory of gravitation and the electromagnetic field in the form suggested by BECHERT 1 has solutions which correspond to the model of a classical particle of mass Moo and charge Q. We shall assume that the coefficient of gravitation χ is not a constant but a field function. The equation of motion is derived for this case. It shows that a suitable choice of the field function χ leads to a correct COULOMB field as well as to a correct gravitational field (corresponding to Q and Mo) in great distance from the particle. The extension of the particle is characterized by the classical radius L=Q2/Moc2 of the particle, it holds together by the balance between COULOMB force and gravitation. The specific charge turns out to be a typical function of the distance from the center of the particle.
