Abstract content <br> &nbsp; (Max 300 words)

Nuclear fission is commonly known as a process where a heavy nucleus such as Uranium decays into two fragments of roughly equal mass. On accasion instead of a decay into two parts a process known as binary fission, the nucleus can decay into three fragments. In this decay channel known as ternary fission, the nucleus splits into three fragments with the third particle being too light compared to the main fission fragments

Collinear Cluster Tripartion

Some years ago the Flerov Laboratory of Nuclear Reactions (FLNR) at The Joint Institute for Nuclear Research (JINR) while perfoming experiments at the FOBOS spectrometer observed some unusual structures in the mass mass plots of 248Cm(sf) and 252Cf(sf) with a yield of -105-106 with respects to binary fission [1]. These observations were treated as indications of a new type of nuclear transformation which later came to be known as Collinear Cluster Tripartion or CCT. CCT is a ternary fission mode where the decay partners fly apart almost collinearly with at least one of them being the magic nucleus [2]. Soon after these observations a number of experiments have been carried by the Flerov Lab in search of the CCT phenomenon. This paper looks at the experimental work done over the years in search of the CCT mode, and highlights some important results of the experiments carried out by the Flerov Lab from the FOBOS setup to the current Light Ions Spectrometer (LIS) experimental setup.
