Neutral multi-MeV/u particles from laser-induced processes in ultra-dense deuterium D(0): accurate two-collector timing and magnetic analysis I doubt that fusion of deuterium is at the bottom of the explosive reaction seen in the Leif Holmlid experiment. I believe that what Holmlid has reproduced is what takes place in the Papp engine. Papp first produced this reaction using water, but changed his technology when the water eroded the inside of his cylinder. He then turned to noble gases to produce the nano particles that cluster together and then explode under the stimulation of an electric arc. I doubt that those noble gases would support a fusion reaction as Holmlid imagines. There is Coulomb explosion of nano particle based clusters involved that produce shock waves and the expansion of gas but no heat. The reaction is most probably a LENR reaction that transfers its energy production to the nano-particle cluster in which the reaction occurs. The Rossi reaction is confined to the surface of the nickel micro particles there rydberg hydrogen amplifies the catalytic type reaction that produces heat then the SPP soliton explodes. The Papp reaction is a plasma based reaction that is free ranging and centered withing clusters of nano particles. In the Papp reaction, XUV and soft X rays produced by the arc or laser excite the clusters instead of heat to generate the coulomb explosion. The Bosenova is the explosive mechanism that imparts energy to the fragments of the cluster. In the Rossi reaction, the nickel micro particle produces the heat based dipole motion that accumulates in the SPP solitons. When the Bosenova explodes, the XUV and soft x-rays are thermalized in the electron clouds to the atoms in the reactor structure. The the Papp reaction, the Bosenove imparts its energy directly to the structure of the cluster. This energy blows the cluster apart and the fragments of the cluster carry the energy away through explosive expansion.
