Shamim, I. Siddiqui, L. Windholz] We present 39odd and 15even parity newly discovered fine structure levels of PrI with low angular momentum: J=1/2, 3/2 and 5/2. Spectral lines in the range 4200Å to 7500Å were experimentally investigated using laser induced fluorescence spectroscopy in a hollow cathode discharge lamp. The levels were discovered by analysis of the recorded hyperfine patterns of the investigated transitions. With the help of these levels, 119spectral lines were classified directly by laser excitation and 127 lines were classified as fluorescence lines.
