Thaddeus, P., and M.N. McDermott, 1963: Level Crossings in the (5s5p) 3P1 State of Radioactive Cd107 and Cd109. Phys. Rev., 132, 1186-1190, doi:10.1103/PhysRev.132.1186.

Four level crossings, which obey the selection rule ΔmF = 2, have been detected for hyperfine levels in the (5s5p)3P1 state of both 6.7-h Cd107 and 470-day Cd109 by observing the change in intensity at 90° of the resonance fluorescence of the 3261 Å intercombination line. The hyperfine interaction constants found from an analysis of the crossing point fields, and corrected for interaction with the adjacent fine structure states of the 5s5p multiplet, are A107 = -853.543(6) Mc/sec, B107 = -163.279(5) Mc/sec, A109 = -1148.784(7) Mc/sec, B109 = -165.143(5) Mc/sec. The ratios of the magnetic-dipole moments, and the electricquadrupole moments, to within the effect of hyperfine anomalies, are μ107 / μ109 = 0.742997(8); Q107 / Q109 = 0.98871(4).
