Jones, your description below about metallic hydrogen stimulates me to wonder about atoms, molecules, particles, and condensed matter. Obviously a single atom of H is not metallic hydrogen. A single molecule of hydrogen is more "dense" than the H/D(1) species of Rydberg matter. I don't think anyone would categorize an ordinary H2 molecule as metallic or condensed matter. The X(1) species of Rydberg matter is shown to exist in particular for H/D and the alkali metals having commonly 7 or more atoms. Are these Rydberg clusters better described as large molecules? A small particle of metal? Generalized condensed matter? How do you ascribe mass density to something only one atomic layer thick? It is interesting to consider.
The Rydberg matter "snowflakes" called X(1), where X is usually an alkali metal, are called Rydberg because the electron orbitals are highly excited Rydberg states in high order flattened (nearly planar) orbitals. The nuclear separation of H(1) is bigger than that for the H2 molecule. Existence for X(1) Rydberg matter particles (clusters, molecules) is well reproduced, modeled, measured, and is utilized by many based on the well described characteristics of the snowflakes obtained, in a large part, from rotational spectroscopy. The existence of Holmlid's ultra-dense form is not reproduced, and what form it might take is completely speculative. The evidence for it appears to be solely from the accelerated species found in supposed Coulomb Explosion (CE). Why is this species not be examined by conventional rotational spectroscopy, as has been used to verify the existence of the X(1) Rydberg matter? I would think that the comprising atoms could NOT be in a DDL state, because if they were, they would not be susceptible to photonic ionization (DDL states are supposed to have too little angular momentum to form a photon), which Holmlid claims causes CE and is his basis for the existence of the D(-1) / D(0) state of matter in the first place. Since the D(-1)=D(0) matter is supposedly susceptible to photo-ionization and CE, it seems like it should also be detectable in a rotational spectrum.
