Based on two alpha-particle chains the Joint Working Party (JWP) Report assigns the priority for discovering element 112 to work done in 1996 and 2002 at GSI, Darmstadt. By doing this it ignores the data presented to the JWP about the discovery of this element already back in 1971 by Marinov et al. In those measurements about one hundred fission fragments were observed from two Hg sources separated from two W targets irradiated with 24 GeV protons. Furthermore, the masses of the fissioning…

Correlations in nuclear interactions between ECM/u and unexplained experimental observables

A new concept is introduced for the classification of "unresolved problems" in the understanding of interactions in thick targets irradiated with relativistic ions: The centre-of-mass energy per

Response to the IUPAC/IUPAP Joint Working Party Second Report 'On the Discovery of Elements 110-118'

Back in 1971 fission fragments were observed by us in Hg sources separated from two CERN W targets that were irradiated with 24 GeV protons. The masses of the fissioning species were measured and

Search for Superheavy Elements in Uranium Irradiated with High-Energy Protons

The recent reports of M A R I N O V et al. [1] on the possible production of eka-mercury (Z = 112) in tungsten targets bombarded with 24 GeV protons, have lead many experimenters [2] to initiate

Spontaneous Fission Previously Observed in a Mercury Source

PREVIOUSLY1, we have presented evidence for the possible existence of a superheavy element with atomic number 112. The principal evidence for the possible existence of this element was based on the

Comment on ``Existence of long-lived isomeric states in naturally-occurring neutron-deficient Th isotopes''

In their article ''Existence of Long-Lived Isomeric States in Naturally-Occuring Neutron-Deficient Th Isotopes''[Phys. Rev. C 76, 021303 (2007)], Marinov et al. fail to demonstrate that basic mass

On the Claims for Discovery of Elements 110, 111, 112, 114, 116, and 118 (IUPAC Technical Report)

The IUPAC/IUPAP Joint Working Party on the priority of claims to the discovery of new elements has reviewed the relevant literature pertaining to several claims. In accordance with the criteria for

EVIDENCE FOR THE POSSIBLE EXISTENCE OF A LONG-LIVED SUPERHEAVY NUCLEUS WITH ATOMIC MASS NUMBER A = 292 AND ATOMIC NUMBER Z ∼ 122 IN NATURAL Th

Evidence for the possible existence of a superheavy nucleus with atomic mass number A = 292 and abundance of about 1×10-12 relative to 232Th has been found in a study of natural Th using inductively

DISCOVERY OF LONG-LIVED SHAPE ISOMERIC STATES WHICH DECAY BY STRONGLY RETARDED HIGH-ENERGY PARTICLE RADIOACTIVITY

The reaction 28Si+181Ta has been studied at ELab=125 and 135 MeV. Coincidences between high energy particles from abnormally long-lived states and various X- and γ-rays were observed, e.g. 7.8–8.6

DISCOVERY OF STRONGLY ENHANCED LOW ENERGY ALPHA DECAY OF A LONG-LIVED ISOMERIC STATE OBTAINED IN 16O + 197Au REACTION AT 80 MeV, PROBABLY TO SUPERDEFORMED BAND

The reaction 16O + 197Au has been studied at a bombarding energy of 80 MeV. A group of 5.20 MeV α particles with a half-life of about 90 m has been found in coincidence with characteristic X-rays of

New outlook on the possible existence of superheavy elements in nature

A consistent interpretation is given to some previously unexplained phenomena seen in nature in terms of the recently discovered long-lived high-spin super-and hyperdeformed isomeric states. The Po
