Abstract Using the atomic beam magnetic resonance method, the five hyperfine structure separations in the 4f 3 6s 2 4I9/2 ground state of 59 141 Pr have been measured. The results are:F F′ E FF′ * /h (MHz) 7 6 6477.913423(17) 6 5 5556.359848 (6) 5 4 4633.023306 (2) 4 3 3708.201146 (5) 3 2 2782.190601(15) From these quantities, the multipole interaction constantsA k,k=1, 2, 3, 4 between the nucleus and the electron shell have been calculated.A 4 especially then served to give the following limit for the intrinsic hexadecapole moment: ¦Q 40¦〈0.4eb 2. Furthermore, theg J -factors of the4 I multiplet have been measured at magnetic fields of 300 Oe. The results are:g J(4 I 9/2)=0.7310371(15)g J(4 I 11/2)=0.9651476(20)g J(4 I 13/2)=1.1063197(40)g J(4 I 15/2)=1.197963 (30) Small corrections due to perturbations by neighbouring fine structure levels are included.
