Lateral distribution of radio emission from cosmic ray air showers
Abstract
Radio pulses from extensive air showers were detected by an experiment performed at the Bolivian air-shower joint experiment (BASJE) array located at an altitude of 5200 meters and geomagnetic latitude of 4 deg S on Mt. Chacaltaya in Bolivia. Five log-periodic antennas were used to detect the radio pulses. Four of these antennas were operated in a broad band mode (pre-detector bandwidth = 54 MHz), narrow band (3.5 MHz) mode; the narrow band channels, which were tapped off the broadband signal, were located at frequencies of 55 MHz, 83 MHz, and 175 MHz. Three hundred and thirteen showers out of 2340 had detectable radio pulses. Thirty events, arriving within the half power cone of the antennas and having a radio pulse in at least three antennas, were used to study the lateral distribution of radio pulses which was found not to be a simple monotonically decreasing function of distance from the shower axis.
