Zhang suggested the following procedure on page 22 of his report:
- Heat above 100 °C
- Apply a vacuum
- Cool down to room temperature
- Admit 1.5 ml D2 to 0.3 MPa (3 bar)
- Let it soak for 24 hours
- Apply 77W power for heat measurements
Apparently the excess heat event was short-lived but repeatable. When it would completely subside, D2 would be removed, then admitted again at 3 bar. The main difference from Mizuno appears to be the operating pressure, but the report does not make it entirely clear if pressure was decreased just before increasing temperatures.
Sounds like these experiments in some implementations are hydrogen and input energy starved. can What you have said strikes a nerve and i think you are very close to a true interpretation. These penitrating "nuclear fragments" that are neutral and dont ionise could be atomic dense hydrogen instead of neutrons possibly the reactions are not as energetic as the fusion assumtion might entail but happen more frequently or at a faster rate. How sure are we that these particles are moving at 10s of MeV? And if they are how sure are we that the energy imparted came from one originating nuclear reaction? Could be collective energies released by multiple reactions being transferred to a few particles by the lattice then ejected. I would propose these non-ionizing neutral particles are a lower energy form of atomic hidrogen that decays because it is only stable in a picoscale bond with another nuclei. Who knows though 😉.
