Resumen:
We report on the detection of HCO+ and 12CO
emission in the rotational transition J = 1-0 in the vicinity of the
shock front at the southern border of the supernova remnant RCW 103,
where previous infrared observations suggest an interaction with a
molecular cloud. The observations were carried out with the Australian
Millimeter Radiotelescope at Mopra. We observed a depletion of
HCO+ behind the supernova shock front. In addition, we
studied the interstellar medium over an extended region towards RCW 103
based on archival λ 21 cm Hi line observations from the Australia
Telescope Compact Array (ATCA) and the Parkes Telescope. No atomic gas
was observed in emission in coincidence with the molecular feature. This
absence was interpreted in terms of self-absorption processes.
