Scientific paper

It is shown that shocks propagating in dense molecular regions will lead to a decrease in HCO(+) relative abundance, in agreement with previous results by Iglesias and Silk (1978). The shock enhancement of HCO(+) detected in the supernova remnant IC 443 by Dickinson et al. (1980) is due to enhanced ionization in the shocked material. This is the result of the material penetrating the remnant cavity where it becomes exposed to the trapped cosmic rays. A similar enhancement appears to have been detected by Wootten in W28 and is explained by the same model.
