The result follows other attempts to understand similar fission processes
of new theoretical approaches to the fission process.
dynamics of the fission processes, at least for nuclei located in the region
The mechanisms underlying both fusion and fission have been described many times, principally by White (1945, 1973) with modifications by John and Freeman (1975).
Centric fission is the consequence of a break within the centromere of a single metacentric producing initially two structural telocentrics whose raw ends have the capacity to fuse after replication.
Figure 1 shows a simplified interrelationship of fusion and fission when fusion occurs through the centric region only.
pendula 2n = 24 (4 M + 6 st + 2 t + 12 T) - differ by a single homozygous fusion or fission (Mattsson, 1971).
These data indicate that fusion or fission is responsible for the observed karyotypic variation.
The combined data demonstrated considerable homology between M types from one group of species and st types from the x = 11 group, confirming a fusion or fission relationship between them but raising the question of the evolutionary connection between the t and st chromosomes and the manner of their differentiation.
Addressing that problem, Kurita (1988b) favored the view that x = 6 was the original basic number for the genus and that fission produced complements of 2n = 22 t which, in the more northern species, were converted into sts by pericentric inversion.
For certainty, however, the scientific community at large requires specific kinds of confirmation, particularly the identification of the products of the fission or the alpha decay to see that they are the nuclei that nuclear dynamics would expect to come from the transuranic element in question.
Experimenters need to identify the products of such unusual fission or other radioactivity to determine precisely what is going on.
Another possibility is to look for evidence of spontaneous fission activity in meteoric material and also in hot brines taken from abyssal fractures of the earth's crust.
However, the average number of spontaneous fission neutrons turned out rather small, close to the value observed in the fission of actinide nuclei.
