A. Canosa et al., REACTION OF ANTHRACENE WITH ATOMIC IONS OF INTERSTELLAR INTEREST - A FALP MEASUREMENT AT ROOM-TEMPERATURE, Chemical physics letters, 245(4-5), 1995, pp. 407-414
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 s
pectrometer apparatus. Reactions proceed with rate coefficients of res
pectively 5.2 X 10(-9), 3 X 10(-9), 1 X 10(-9) cm(3) s(-1) for He+, C and Ar+. The results were obtained with an uncertainty of about 30% a
nd were found to be close to the Langevin rate. The nature of the prod
ucts has also been investigated. More particularly, the evidence for c
arbon accretion and for the production of doubly charged species is di
scussed.
