Scientific paper

Interstellar C_2 bands D-X (2313 Ang) and F-X (1342 Ang) in the spectrum of X Per were detected in the archive echelle spectra acquired by the Goddard High Resolution Spectrograph (GHRS) aboard the Hubble Space Telescope. The population of C_2 rotational levels was determined from the rotational lines in the D-X band to obtain kinetic temperature T_k=45+/-15 K. The total C_2 column density N(C_2)=(3.4+/-0.5)*1013 cm^{-2} was calculated using the D-X band with f-value of 0.0545. The analysis of F-X band with an adopted f-value of 0.1 gave different population of rotational levels of C_2. Possible reasons of this discrepancy are discussed. The FWHM of the C_2 line profile was estimated to be Delta V=2.7+/-1.0 km/s.
