The primary energy spectrum with the Linsley method correcting heavy primary effects in the LAAS experiments

The compact EAS Extensive Air Shower (EAS) array (200 m 2 ) and the Linsley method have been used with the aim to observe the primary energy spectrum. The spectral indexes α proton and α iron are obtained as − 2.46 ± 0.17 and − 3.08 ± 0.24, respectively, in the primary energy region of 10 16 eV − 10 18.5 eV in the single observation of the compact EAS array. Additionally, α proton and α iron are obtained as − 3.12 ± 0.13 and − 3.52 ± 0.17, respectively, in the same primary energy region in the observation by restricting the zenith angle of EAS events.
