The SFiNx Detector System

A new detector system for investigating the properties of spontaneous fission short-lived transuranium nuclei has been created. This consists an assembly double-sided silicon strip detectors surrounded by 116 proportional neutrons counters filled with 3He. The neutron registration efficiency is 54.7 ± 0.1%. tested in experiment characteristics 252No isotope. experimental data on yields are compared previously published results. average number per act ( $$\bar {\nu }$$ = 4.25 $$ \pm 0.09) and multiplicity distribution prompt obtained. true form reconstructed via a statistical regularization.
