Clusterization in heavy cold nuclei

Abstract

Abstract A cluster is broadly understood to be an object which keeps its identity in a larger scale system. Manifestations of clustering can be revealed in very different size systems from exotic nuclei to galaxies. In our work we search for cluster effects in low energy fission of heavy nuclei. In the series of experiments carried out with the spectrometers based both on the gas filled (FOBOS spectrometer and its modifications) detectors and mosaics of solid-state detectors (setups at the beams of alpha-particles and deuterons, COMETA spectrometer) using the “missing mass” method and with the direct detection of three decay partners, we have discovered a new type of the ternary decay of heavy nuclei dubbed by us “collinear cluster tri-partition (CCT)”. The most interesting aspects of both the original methodic used and the physics of the effect observed are discussed in the presented report.
