Fluorescence in damp air and comments on the radiative life time

Astrophysics 2007-05-23 v1

Abstract

Photon yields in damp air excited by an electron using a Sr90 β\beta source are compared withthose in dry air. Water vapors considerably reduce the yields, however, a further study is needed to evaluate the effects on the energy estimation of ultrahigh-energy cosmic rays. The relation of fluorescence efficiency to the life time of de-excitation by radiation is discussed.
