Abstract
Spectroscopy of buffer-gas cooled vanadium monoxide (VO) is performed in the presence of a magnetic trapping field and at low field. VO is c reated via laser ablation. A helium buffer gas, chilled by a dilution refrigerator, cools 10(12) VO molecules to 1.8+/-0.2 K within 10 ms. T he measured rotational temperature is 1.5+/-0.8 K. Spatially resolved Zeeman spectra allow the magnetic broadening terms of several optical transitions to be determined. The density of VO decays with a characte ristic time of 60 ms, thus precluding the observation of trapping. (C) 1998 American Institute of Physics.
