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 m²) and the Linsley method have been used with the aim to observe the primary energy spectrum. The spectral indexes αproton and αiron are obtained as -2.46 ± 0.17 and -3.08 ± 0.24, respectively, in the primary energy region of 1016 eV - 1018.5 eV in the single observation of the compact EAS array. Additionally, αproton and αiron 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.
