| Abstract: | Summary The combined (EAS+EC) ?Hadron? experiment was made at Tien-Shan Station during 1985–1991. A large statistic of gamma-hadron
families, combined with EAS, is now analysed. The result of the leader effect disappearance forN
e>107 was reported earlier and at this Conference too. Here we present new results about the existence of Super Young Showers (SYS)
with ageS<0.1, containing gamma-hadron families with visible energy ≥10 TeV. Namely, SYS have anomalous soft-energy spectra of particles
at gamma-hadron families. These events may be connected with Young Air Showers (YAS) and Narrow Air Showers (NAS).
Paper presented at the Special Session on very high-energy cosmic-ray interactions (superfamilies) of the XXIV International
Cosmic-Ray Conference, Rome, August 28–September 8, 1995. |
