Transition probabilities of Pr II-lines emitted from a ferroelectric plasma source.
Abstract
An argon-praseodymium plasma was generated under atmospheric pressure between a ceramic ferroelectric plate and a praseodymium plate. The system of plates was connected to an acoustic frequency supply. The plasma radiation was analyzed in the spectral range from 2000 to 7000 Å by using a grating spectrograph with a linear dispersion near 1 mm/Å, adopted to photoelectric measurements. The emission spectrum of praseodymium was recorded and the intensities of a few hundred lines were measured. Transition probabilities were determined for 62 Pr II-lines, using available lifetime data for excited levels and measured branching ratios of the corresponding lines.
