The analysis of some LENR experiments provided in my article in General Science Magazine  and in my recent book, Physics of Nuclear Fusion , leads to the suggestion what could be the Rossi catalyzer used in his E-cat reactor. In the E-cat reactor of Andrea Rossi and Hyperion reactor of Defkalion  one and a same nuclear reaction Ni + H -> Cu is reported. Despite some differences in the technical approach, the analysis unveils that one and a same physical phenomenon takes place in both rectors. In Hyperion reactor the high voltage discharge firstly causes a dissociation of the molecular to atomic hydrogen and then obtaining of a proper Rydberg state of the hydrogen. According to the source , Strongly magnetized Rydberg atoms and plasmas continue to attract interest for several reasons; they represent a well-known paradigm for quantum-chaos, exhibit interesting collective and collisional properties and may provide a superior route towards simultaneous atom-plasma confinement and control.
My theoretical work [1,2,5] and experimental research on cold plasma  reveals the existence of a specific state of the Rydberg atom of hydrogen in which the orbiting electron does not emits optical spectrum, while its magnetic moment becomes detectable. This is a new distinguishable feature of this state, so it is called ion-electron pair. The stability of this ion-electron pair is kept by the attractive Coulomb forces, while the electron rotating around the heavier ion (proton in case of hydrogen) drives the pair due to its anomalous magnetic moment. The electron has 658 times greater magnetic moment than the proton, so the magnetic fields from a large number of ion-electron pairs combine constructively in clusters creating a much stronger magnetic field. The strong magnetic field detected during the live test of Hyperion reactor broadcasted on 22-23 July 2013 might be a signature of this effect. The magnetic field of some ion-electron pair interacts with the nuclear magnetic moment of the nucleus that is in a proper nuclear spin state. As a result the Coulomb barrier is overcome, so the proton from the hydrogen ion-electron pair is fused to the nickel nucleus converted it to a copper. The proper nuclear spin facilitates the cold fusion process, according to Ruggero Santilli, as discussed in . In the Hyperion reactor, the creation of ion-electron pairs (Rydberg atoms) is caused by the high voltage plasma discharge. In the E-cat reactor, this phenomenon might be invoked by beta particles emitted by some radioactive isotopes. This could be the secret catalyzer used by Rossi in his E-cat device. Practically it is not convenient to mix the radioactive beta emitters with the nickel powder. It is more appropriate to place them at the outside wall of the container holding the powder. Then the external shield of beryllium used in the E-cat reactor might play a double role: shielding the external environments from the beta particles and shielding from some radiation obtained due to nuclear reactions. In provided public test Rossi did not allow close examination of the E-cat device by sensitive detectors.
The process of ion-electron pair formation, its properties and interaction with the proper nuclear spin is described in the book . Additionally a new method was suggested for estimation of the position of the proton prior to the nuclear fusion. The analysis and the new method suggest also a possibility for other nuclear reactions using chromium and hydrogen. It is shown that the right selection of heavier element isotope is important for successful cold fusion reaction with minimum radioactive by-products.
In conclusion, the Rossi secret could be uncovered by experimenting with beta emitters. There is a large variety of such isotopes produced for medical purpose and defectoscopy.
