****************************************************** PR # 31053 We propose to observe three candidates of Galactic sources with jets, GT2318+620, GRS1758-258 and G127.11+0.54. They are selected with the se criterions: 1. jet-like structure is observed in radio band, 2. lo cated in Galaxy, 3. X-ray emitter, 4. pointing observation has never been performed in ASCA band. If Doppler shifted feature is found in a spectrum, it would be conclusive evidence of jets. As the case of SS 433, various information of the system such as energy, temparature gr adient and ionization structure of the jet, geometrical parameters, m ass of the compact object, etc. can be derived from the ASCA data. B ecause little Galactic jet sources are known so far, new samples of j ets must greatly contribute to the study of astrophysical jets. ******************************************************
