Experimental transition probabilities for Mn II spectral lines

Transition probabilities for 46 spectral lines of Mn II with wavelengths in the range 2000-3500 angstrom have been measured by CSigma laser-induced breakdown spectroscopy (C sigma-LIBS). For 28 of the lines, experimental data had not been reported previously. The C sigma-LIBS method, based in the construction of generalized curves of growth called C sigma graphs, avoids the error due to self-absorption. The samples used to generate the laser-induced plasmas are fused glass disks prepared from pure MnO. The Mn concentrations in the samples and the lines included in the study are selected to ensure the validity of the model of homogeneous plasma used. The results are compared to experimental and theoretical values available in the literature.
