Abstract
The magnetic circular dichroism and absorption spectra of Ta atoms isolated in an Ar matrix have been observed in the range 220 - 540 nm. Over sixty-five bands in the MCD spectrum were assigned by a comparison of signs and intensities of the $C_{o}$ terms with the J and gf values of the gas phase spectrum. An average shift to the blue of $786cm^{-1}$ (range: $573-976cm^{-1}$) was found for matrix spectrum. A g factor of $0.42\beta$ for the ground state of Ta in an Ar matrix was obtained from the temperature dependence of $C_{o}$ type band at 522.3 and 504.4 nm.
