Scientific paper

Interstellar H2S has been detected toward the cold, dark clouds L134N and TMC 1. Total column densities at the SO peak of L134N and the NH3 peak of TMC 1 are found to be about 2.6 X 10 to the 13th/sq cm and 7.0 X 10 to the 12th/sq cm, respectively. The results suggest that grain surface reactions may play a major role in the synthesis of H2S in cold, dark clouds.
