Reaction of anthracene with atomic ions of interstellar interest. A FALP measurement at room temperature

Résumé

We present the results obtained on studying the reaction of anthracene with some atomic ions of interstellar interest (He+ and C+) and with Ar+. Rate coefficients have been measured at room temperature (293 K) in afterglow experiments using flowing afterglow Langmuir probe-mass spectrometer apparatus. Reactions proceed with rate coefficients of respectively 5.2 × 10−9, 3 × 10−9, 1 × 10−9 cm3 s−1 for He+, C+ and Ar+. The results were obtained with an uncertainty of about 30% and were found to be close to the Langevin rate. The nature of the products has also been investigated. More particularly, the evidence for carbon accretion and for the production of doubly charged species is discussed.
