“…Such results are included here to give direct evidence with another method that muons are indeed formed by the laser-induced processes. The processes that give muons are both laser-induced [5] and spontaneous [3]. A typical experiment is shown in Fig 3, where both a plastic scintillator (PS) and an Al metal converter [4] are used to detect the muons and other particles from the laser-induced nuclear processes in the D(0) layer on the target.…”

“…One decay channel of low probability for positive kaons can also give negative pions and thus negative muons [51]. However, the detection of muons through muon decay and capture [3–5,60] with an example in Fig 3 (beta-like distribution) requires that negative muons are formed at quite large intensities. The possibility that seems to exist in the model used here is formation of negative muons by decay of neutral kaons .…”

“…Emission of muons by spontaneous and laser-induced processes in ultra-dense deuterium D(0) [1,2] was recently reported from our group [3,4,5]. Ultra-dense protium p(0) [2,6] is quite similar in its properties to ultra-dense deuterium D(0).…”

Large signals of charged light mesons are observed in the laser-induced particle flux from ultra-dense hydrogen H(0) layers. The mesons are formed in such layers on metal surfaces using < 200 mJ laser pulse-energy. The time variation of the signal to metal foil collectors and the magnetic deflection to a movable pin collector are now studied. Relativistic charged particles with velocity up to 500 MeV u-1 thus 0.75 c are observed. Characteristic decay time constants for meson decay are observed, for charged and neutral kaons and also for charged pions. Magnetic deflections agree with charged pions and kaons. Theoretical predictions of the decay chains from kaons to muons in the particle beam agree with the results. Muons are detected separately by standard scintillation detectors in laser-induced processes in ultra-dense hydrogen H(0) as published previously. The muons formed do not decay appreciably within the flight distances used here. Most of the laser-ejected particle flux with MeV energy is not deflected by the magnetic fields and is thus neutral, either being neutral kaons or the ultra-dense HN(0) precursor clusters. Photons give only a minor part of the detected signals. PACS: 67.63.Gh, 14.40.-n, 79.20.Ds, 52.57.-z.

CR-39 detectors were used to detect high energy particles produced during Pd/D co-deposition. Upon completion of the experiments, the detectors were subjected to either microscopic examination, scanning using an automated scanner to obtain quantitative information on the tracks, sequential etching, or linear energy transfer (LET) spectrum analysis. Both the sequential etching and LET analysis allowed speciation of the particles that caused the tracks as well as estimating their energies. In these experiments it was shown that the tracks coincide with the placement of the Pd deposit. The average number of tracks obtained as a result of 1 Corresponding 2 Pd/D co-deposition is more than 133 times greater than that found in the background. In this communication, the results of microscopic examination, scanning, and LET analysis are discussed.

The solar wind proton ejection mechanism: Experiments with ultradense hydrogen agree with observed velocity distributions

Ultradense hydrogen H(0) is a very dense hydrogen cluster phase with H‐H distances in the picometer range. It has been studied experimentally in several publications from our group. A theoretical model exists which agrees well with laser‐pulse‐induced time‐of‐flight spectra and with rotational spectroscopy emission spectra. Coulomb explosions in H(0) in spin state s = 1 generate protons with kinetic energies larger than the retaining gravitational energy at the photosphere of the Sun. The required proton kinetic energy above 2 keV has been directly observed in published experiments. Such protons may be ejected from the Sun and are proposed to form the solar wind. The velocity distributions of the protons are calculated for three different ejecting modes from spin state s = 1. They agree well with both the fast and the slow solar winds. The best agreement is found for H(0) cluster sizes of 3 and 20–50 atoms; such clusters have been studied experimentally previously. The properties of ultradense hydrogen H(0) give also a few novel possibilities to explain the high corona temperature of the Sun.
