Scission Point Calculations and Physical Treating of the 'Ni-bump' in 252Cf (sf)

In a series of the experiments at different time-of-flight spectrometers of heavy ions we have observed manifestations of a new at least ternary decay channel of low excited heavy nuclei. Due to specific features of the effect, it was called collinear cluster tri-partition (CCT). The experimental results obtained initiated a number of theoretical articles dedicated to different aspects of the CCT. In the report we compare the theoretical predictions with our experimental data, only partially published so far. The developed model of one of the most populated CCT modes that gives rise to the so called “Ni-bump” is discussed

Applications of (3)He neutron detectors

Neutron detectors with (3)He-filled proportional counters are described. The use of these detectors in measuring the probability of neutron emission (in particular, multiparticle neutron emission) after the beta decay of neutron-rich nuclei and in studying rare events of spontaneous fission of superheavy nuclei is considered
