摘要：

Criteria for selecting proton events among the total sequence of events from primary nuclei of cosmic rays with zenith angles theta < 20A degrees are analyzed in the energy region of E (0) a parts per thousand 10(16) eV. These criteria are concretized for the case of the SPHERE-2 experiment geometry. The QGSJET-I and QGSJET-II model calculations show that the criteria based on the shape of the transverse distribution of Cherenkov light allow detection of more than 10% of proton events and rejection of 99% nuclear events.
