For comparison, Rossi stated his current theory in a recent interview.
"“My theory is that a proton from a hydrogen atom enters, by the quantum tunneling effect, into a nucleus of Li-7 (i.e., a lithium nucleus of atomic weight 7), forming a nucleus of Be-8 (i.e., a beryllium nucleus of atomic weight 8), which then decays in a few seconds into two alpha particles (helium nuclei), accompanied with the release of significant nuclear energy."
