Radio Emission of Air Showers with Energy E${}_0$ $\ge$ 10${}^{19}$ eV by Yakutsk Array Data

Abstract

In this paper, we present results obtained from the measurements of radio emission at frequency of 32 MHz with energy more than 10${}^{19}$ eV. Generalized formula that describe lateral distribution and depends on main characteristic of the air showers: energy E${}_0$ and depth of maximum X${}_{max}$ was derived. The formula has a good agreement with data at average and large distances from shower axis. Employing the ratio of radio emission amplitude at distances 175 m and 725 m we determined the depth of maximum X${}_{max}$ for air shower with energy 3.7$\cdot$10${}^{19}$ eV, which in our case is equal to X${}_{max}$ = 769$\pm$34g$\cdot$cm${}^{-2}$.
