Kaiser (1953) [1] has shown how it is possible, from statistical studies of radio echoes from meteor trails, to obtain values of the exponent s in the assumed equation for the number of meteors n(α) of line density α where αm is the maximum electron line density (number of electrons per cm.) produced in the trail of a meteor. If the simple theories of the meteor ionization process are correct, αm is proportional to the meteor mass m, so that from radio echo studies it should be possible to obtain a measure of the meteor mass distribution: where n(m) is the number of meteors with mass in the range from m to m + dm.
