The discovery of methanol masers at 107 GHz.

Abstract (from CDS):

A new methanol maser line at 107GHz was discovered in five galactic sources. All of them are known Class II methanol masers. Toward Class I methanol maser sources, the 107-GHz line was found in absorption, or as rather weak quasi-thermal emission sources. The detection of these new methanol masers supports an assumption that the level population inversion is due to overpopulation of some K ladders relative to neighbouring ladders.
