Abstract: The energy spectrum of a radio pulse induced by a cascade shower in the lunar regolith is derived. The transverse dimensions of the shower and a nonuniform distribution of excess electrons on the disc radius are taken into account. The spectrum in the high-frequency region is radically different from earlier results which are used in experimental studies. The maximum intensity of the field lies in the range from 500 to 600 MHz. In the frequency band from 1.6 to 2.3 GHz the radiation intensity decreases by several orders of magnitude. By the authors’ opinion, this is one of the reasons for the events absence in the experimental investigations, which are closed to the z0 burst models.
