Proposal Title: HI self-absortion study of dark clouds
ABSTRACT:
We propose observing atomic hydrogen inside dark clouds through 21 cm self-absorption. The OH (1665 MHz and
1667 MHz) will be observed simultaneously. With highest angular resolution and nest velocity resolution of HI
dark-cloud maps ever achieved, the data set will reveal velocity structure and column density in HI and provides a
good look at important chemistry issues, e.g., ionization ratio within dark clouds.
