dc.description.abstract | The energy spectrum of electrons produced in molecular gas by interstellar cosmic rays (CRs) is rigorously calculated as a function of gas column density N traversed by the CRs. This allows us to accurately compute the local value of the secondary ionization rate of molecular hydrogen, ${\zeta }_{\sec }(N)$ , as a function of the local primary ionization rate, ζ<SUB>p</SUB>(N). The ratio ${\zeta }_{\sec }/{\zeta }_{p}$ increases monotonically with N, and can considerably exceed the value of ≈0.67 commonly adopted in the literature. For sufficiently soft interstellar spectra, the dependence ${\zeta }_{\sec }/{\zeta }_{p}$ versus N is practically insensitive to their particular shape and thus is a general characteristic of the secondary CR ionization in dense gas. | en_US |
