Abstract

Calculations are presented of the amount of excess ionization produced in the lower ionosphere by various transient X- and γ-ray bursts under different assumptions about the incident spectrum and the ion recombination rates in the ionosphere. These calculations show that the bursts will have only a small effect on the ionosphere, due in part to their short duration. An experiment has been started to measure the power spectrum of the phase and amplitude of the night-time fluctuations of a CW signal in order to determine if it is possible to improve the sensitivity of the ionospheric technique by using the transient nature of the bursts. Preliminary results from this experiment are presented.
