The Modern Status of Anomalous Delayed Particles Effect in the "Knee" Region EAS According to the Data of Tien Shan Mountain Station

Attempts to explain the extra high multiplicity neutron events having peculiar prolonged time distributions of particle intensity ("neutron bursts") without any exotic assumption concerning the EAS nature lead to contradictions with the usual models of EAS cascade development. The supposition that these events could be a consequence of experimental distortion demands again the presence of enormous hadron flows 50-100 times greater than the EAS theory predicts.
