The hyperfine structure of about 200 lines of the neutral tantalum atom was investigated by means of Doppler limited laser spectroscopy. From the spectra we have deduced the magnetic hyperfine interaction constants A and the electric quadrupole interaction constants B of 8 levels with even parity and 81 levels with odd parity. Further, we have discovered 24 new levels of even parity and 11 new levels of odd parity.
