Abstract

Simultaneous observations of the six transitions of SiO for 106 late-type stars were made. The SiO maser emission was detected in 83 stars. The v = 3 maser emission was detected in eight stars, and the 29SiOv = 0 emission in six stars. The 29SiO v = 0 emission is stronger and narrower than that of 28SiO, suggesting that the 29SiO emission is masing.
