Increase in the Absorption Length of Inclined Extensive Air Showers with Different Selection Types

Original · EN

The dependence of the number of extensive air showers (EAS) on the zenith angle is obtained in groups with a constant solid-angle step with different election types at separations between stations of 500 and 1000 m by using the Yakutsk EAS array data. A bend point is formed at the zenith angle approximately of 50 deg. This point shifts with the increasing energy in the direction corresponding to the shift of the cascade-curve maximum depth with the variation of energy. The boundaries of change of these dependences obtained separately at the distances between stations of 500 and 1000 m are different that may be caused by the uncertainty of the lateral distribution function (LDF) used. Thereby, energies of showers detected by the stations with a different separation are not joined.
