Experimental MoII oscillator strengths

Experimental branching fractions (BFs) of Mo (II,) ranging in wavelength fr om 1970 to 4370 Angstrom, have been measured from intensity calibrated spec tra recorded with the Lund UV Fourier transform spectrometer (FTS). Radiati ve lifetimes for 10 levels have been measured using the method of laser-ind uced fluorescence (LIF). Combining BFs with new as well as previously measu red lifetimes, 16 in total, oscillator strengths of 91 lines were derived. Seven transitions are resonance lines involving the ground state. The BF re sults are compared with calculations made with the Cowan code and the f-val ues are compared with previously published data. Improved wavelengths from an ongoing term analysis are also reported.
