摘要
A search for the 9(-1)-8(-2) E, 4(3)-5(2) A+, and 4(3)-5(2) A- methanol lines at 9.94, 9.98, and 10.06 GHz, respectively, was undertaken with the 43 m radio telescope at Green Bank. From a sample of 11 sources three were detected in emission for the 9(-1)-8(-2) E line, Orion-KL, Sgr B2, and W33-Met. The line in W33-Met shows maser properties; in Orion-KL and in Sgr B2 the line is thermal.
