Response to Comment on Ultradense protium p(0) and deuterium D(0) and their relation to ordinary Rydberg matter: a review [Physica Scripta 94 (2019) 075005]

Leif Holmlid

In this answer to the Comment by Hansen and Engelen it is shown, that if there is any violation of the baryon number conservation law in H(0) nuclear reactions, it is not at all of…

Response to "Comment on 'Phase transition temperatures of 405-725 K in superfluid ultra-dense hydrogen clusters on metal surfaces' [AIP Advances 6, 045111 (2016)]"

Leif Holmlid, Bernhard Kotzias

In this invited response we answer all comments by Engelen and Hansen [arXiv:2207.07844]. We point out that the superfluid and superconductive properties of H(0) have been publishe…

Comment on "K. Hansen, Int. J. Mass Spectrom. 399-400 (2016)51"

Leif Holmlid

The comment by K. Hansen suggests that the time-of-flight mass spectrometry data in one table in our paper from 2103 in IJMS should be due to a proton contamination and correspond…

Neutral multi-MeV/u particles from laser-induced processes in ultra-dense deuterium D(0): accurate two-collector timing and magnetic analysis

Leif Holmlid

Laser-induced processes in ultra-dense deuterium D(0) layers eject multi-MeV u-1 particles using ns laser pulse energies of <200 mJ. Such particles have been observed previously as…

Direct observation of particles with energy >10 MeV/u from laser-induced fusion in ultra-dense deuterium

Leif Holmlid

Nuclear fusion in ultra-dense deuterium D(-1) induced by 0.2 J pulses with 5 ns pulse length ejects ions with energies in the MeV range. The ns-resolved signal to a collector can b…

Diffuse interstellar bands (DIB): co-planar doubly excited He and metal atoms embedded in Rydberg Matter

Leif Holmlid

The interpretation of the more than 300 diffuse interstellar bands (DIBs) is one of the most long-standing problems in interstellar spectra since the two first bands were reported…

Rydberg Matter clusters of alkali metal atoms: the link between meteoritic matter, polar mesosphere summer echoes (PMSE), sporadic sodium layers, polar mesospheric clouds (PMCs, NLCs), and ion chemistry

Frans Olofson, Patrik U. Andersson, Leif Holmlid

A material exists which links together the influx of meteoritic matter from interplanetary space, the polar mesosphere summer echoes (PMSE), the sporadic sodium layers, the polar m…

Electronic transitions in Rydberg Matter as the source of the unidentified infrared bands (UIR) observed in interstellar space

Leif Holmlid

Rydberg Matter (RM) theory is previously shown to give good agreement with the unidentified infrared bands (UIR, UIB) that are observed in emission from many objects in space. From…
