Detecting torsion from massive electrodynamics

A new method of detecting torsion in the case of massive electrodynamics is proposed. The method is based on the study of spectral lines of hydrogen-like atoms placed in a torsion field, where the interaction energy between the torsion vector field Q and an electric dipole is given by P · Q. All the methods designed so far have been based on spinning test particles interacting with magnetic fields in which the energy splitting is given by S · B on a Stern-Gerlach type experiment. We arrive at an energy splitting of order of 10^–21erg 10^–9eV, which is within the frequency band of radio waves.
