Abstract
The hyperfine structure (HFS) for V I and V II were investigated using the archival data recorded by the Fourier transform spectrometer (FTS) at the US National Solar Observatory (NSO) with a fitting program written by us. The magnetic dipole HFS constant A values for 53 levels of V I between 0 and 52,948 cm−1 and for 56 levels of V II between 36 and 72,952 cm−1 are obtained, of which 46 results for V I and 50 results for V II are reported for the first time, as far as we know. And to our knowledge, so far, the A constants of 370 levels of V I and 76 levels of V II have been measured in literature. The new results obtained in this work supplement more experimental HFS data very useful in astrophysics and atomic physics etc..
