Producing form factor

The dynamic group 0(4,2) of a hydrogen atom is expressed through dynamic variables of four oscillators. Therefore the Coulomb problem can be considered in coherent representation with four coherence parameters. As a result of this approach producing amplitudes were obtained, in which physical process amplitudes are coefficients at powers of the coherent parameters. The producing amplitude is very simple, as a rule. The producing function of the nonrelativistic inelastic form factor of a hydrogen atom has been found. The form factor itself has been found in parabolic quantum numbers. It is expressed through the product of two Jacobi polynomials. A particular case of the ground state excitation is investigated
