Interaction of a current in a superconductor with Mossbauer radiation
Belogurov V. N. , Borzyak A. N., Karklin'sh N. N.
The behavior of the recoilless radiation of a Mossbauer source upon a change in the direction of the current between a superconducting YBa2Cu307 ceramic and a Mossbauer source has been studied. It is concluded that the superconductivity current carriers in this superconductor are pairs of electrons which are coupled by a phonon exchange interaction.
