Measurement of relative oscillator strengths for Mn I. Transitions from levels in the range 0 eV < < 3 eV

We present relative oscillator strengths for 58 lines of Mn I for a range of + 0.19 > log(gf) > −3.795 in the excitation interval 0eV < χ < ∼ 3 eV. The measurements have been made to a relative accuracy of better than 2 per cent using the Oxford furnace tehnique, with full allowance for hyperfine structure using the data of Booth et al. The relative values have been placed on an absolute scale using published lifetime data, to an accuracy of about 7 per cent for the ground state lines and 3 per cent for the excited state lines.
