Abstract (from CDS):
We use a combination of laboratory and astrophysical measurements to determine transition probabilities for the [TIII] lines. Lifetimes for metastable levels in TIII are measured using a laser probing technique on a stored ion beam at CRYRING, MSL, Stockholm. Branching fractions from some of these levels are derived from Hubble Space Telescope/STIS spectra of the SrF. The astrophysical branching fractions are combined with the experimental lifetimes to determine absolute transition probabilities.
We report lifetimes for the TIII levels b4P3/2, b2P1/2, c2D3/2and c2D5/2, in the range 0.29-17 s, and transition probabilities for eight parity-forbidden lines from the levels c2D3/2and c2D5/2, along with uncertainty estimates.
