NEUTRINO FLUX RECORDING METHOD Russian patent published in 2000 - IPC

FIELD: neutrino detectors. SUBSTANCE: method involves measurement of rate of occurrence of radioactive nuclei in neutrino target whose charge is greater by one and number of nucleons smaller by two neutrons compared with that in source working isotopes of neutrino target, as well as determination of neutrino flux by rate of occurrence of these radioactive isotopes. In recording neutrino fluxes use is made of processes in which capture of neutrino by working isotope of neutrino target and radioactive process that follows result in production of three or more particles and not two ones as in known detection method. Such process can be illustrated by reactions during which capture of neutrino yields electrons, dineutrons ((²n)), and nuclei whose positive charge is greater by one and number of nucleons is smaller by two compared with that in source isotopes. EFFECT: improved sensitivity, reduced size of neutrino detectors, enlarged range of low-energy neutrino recorded.
