Search for LiH in the ISM towards B0218+357.

COMBES F. and WIKLIND T.

Abstract (from CDS):

We report a tentative detection with the IRAM 30m telescope of the LiH molecule in absorption in front of the lensed quasar B0218+357. We have searched for the J=0->1 rotational line of lithium hydride at 444GHz (redshifted to 263GHz). The line, if detected, is optically thin, very narrow, and corresponds to a column density of N(LiH)=1.6x1012cm–2 for an assumed excitation temperature of 15K, or a relative abundance LiH/H2∼3x10–12. We discuss the implications of this result.
