A research group in Sweden under Leif Holmlid announced last year it had discovered an dense form of deuterium by a "phase transition from a Rydberg matter state of deuterium, a million times more dense than liquid deuterium." "A much denser state exists for deuterium, named D(-1). We call it ultra-dense deuterium. This is the inverse of D(1), and the bond distance is very small, equal to 2.3 pm. Its density is extremely large, >130 kg / cm3, if it can exist as a dense phase. Due to the short bond distance, D-D fusion is expected to take place easily in this material." This claim is so extraordinary that it must be taken with a great deal of skepticism, even by vorticians; but since Holmlid has an established record of publications about Rydberg matter in the refereed scientific literature, the claim cannot be dismissed as crankiness. Also significant is the relationship of this to claims in the LENR literature - Arata and Kitamura etc, and that of Randell Mills. Is this the same beast as "pycnodeuterium" aka the deep-redundancy "shrinkage" of fractional deuterium? Jones
