Yu. V. Pyatkov,Yu. V. Pyatkov,D. V. Kamanin,W. von Oertzen,A. A. Alexandrov,I. A. Alexandrova,O. V. Falomkina,O. V. Falomkina,N. A. Kondratjev,Yu. N. Kopatch,E. A. Kuznetsova,Yu. E. Lavrova,A. N. Tyukavkin,W. H. Trzaska,V. E. Zhuhcko +14 more
TL;DR: In this paper, experimental results in favour of the existence of a new type of cluster decay called "collinear cluster tri-partition", CCT, are presented based on two different experiments with binary co- incidences and measurements of the masses and energies of the two fragments, as well as using in one of the experiments observables sensitive to the nuclear charge of the fission fragments.

TL;DR: In this article, the results of two different experiments for the study of fission of 252Cf (sf) events in coincidence with neutrons are reported, where two time-of-flight-energy (TOF-E detectors systems have been used.

TL;DR: In this article, a comparative analysis of the high-statistics mass-energy distributions of the fission fragments formed in the 252 Cf(sf) and 249 Cf(n th,f) reactions is performed on the basis of the potential energy surface calculations.

Journal ArticleDOI
True Ternary Fission, Collinear Cluster Tri (CCT) Partition of 252 Cf
TL;DR: In this article, the authors used the term "true ternary fission" for a fission process with three masses of comparable size, A > 35, and measured the masses and energies of the registered two fragments.
