摘要: Radiative lifetimes of 12 odd-parity and 73 even-parity levels Eu I, 26 II, three III have been measured with time-resolved laser-induced fluorescence. These are accurate to ±5%. In addition, I branching fractions Fourier-transform spectrometry. combined the radiative yield absolute transition probabilities for 140 transitions I.
