Abstract (from CDS):

begin{HTML}Five rotational lines of the C8H– ion were observed in the circumstellar envelope of IRC +10216 with the Nobeyama 45m telescope. An improved value of the column density of the C8H radical yielded a [C8H–] / [C8H] ratio of 37% - nearly 4 times larger than the [C6H–] / [C6H] ratio (8.6%) and nearly 1500 times the [C4H–] / [C4H] ratio (0.024%), which may indicate more efficient formation of longer carbon chain anions. The excitation temperature of C8H– (16±2K) derived here is somewhat lower than that of the two smaller anions C6H– (32K) and C4H– (23K) in IRC +10216.
