Abstract:

Specific ionization rate expressions Qz for heavy particles are derived for Polar Cap Absorption events and presented in a form applicable to any atmosphere. Results are given for four types of spectra jE, alpha approximately v E phi alpha for the incident particles 1 monoenergetic and monodirectional, 2 monoenergetic, phi alpha approximately cos sup betaalpha, 3 monodirectional, v E approximately E to the minus nth power, and 4 jE, alpha approximately E to the minus nth power cos sup betaalpha. When the spectrum is assumed to extend to infinite energy, simple analytic forms are obtained for Qz for spectra 3 and 4 for that region of the atmosphere in which the atmospheric depth exceeds the range of the minimum energy particles contained in jE, alpha. Application of the results to obtain ionization rates for other spectral forms is discussed. Author
