N $_{2}^{+}$ and CO $^{+}$ in Comets 122P/1995 S1 (deVico) and C/1995 O1 (Hale-Bopp)

Anita L. Cochran, William D. Cochran, Edwin S. Barker

We observed comets 122P/1995\,S1 (deVico) and C/1995\,O1 (Hale-Bopp) with high spectral resolving power in order to determine the ratio of N $_{2}^{+}$ /CO $^{+}$ in their comae. While we c…
