The results of new studies of decimeter wavelength Hnα and Cnα lines toward galactic nebulae are reported. The observations were made with the 305-m radio telescope of the Arecibo Observatory at 430 MHz (247α and 248α) and 606 MHz (221α). Selected positions in W51, W49, and the Rosette nebula were observed. The observed lines exhibit no pressure broadening; however, this is consistent with the interpretation of the data.
