SV Stepkin, AA Konovalenko… - Monthly Notices of …, 2007 - academic.oup.com
In this paper, we report the detection of a series of radio recombination lines (RRLs) in
absorption near 26 MHz arising from the largest bound carbon atoms detected in space …

LOFAR observations of decameter carbon radio recombination lines towards Cassiopeia A
