Atomic-Beam Measurement of the Hyperfine Structure and Nuclear Moments of Iodine-131

The nuclear magnetic dipole and nuclear electric quadrupole interaction constants a and b were measured in 8-day I/sup 131/ by an atomic beam magnetic resonance experiment. The results were a = 575.903 plus or minus 0.007 Mc/sec, b = 578.866 plus or minus 0.075 Mc/sec. The zero-field hyperfine split...

Zusammenfassung:	The nuclear magnetic dipole and nuclear electric quadrupole interaction constants a and b were measured in 8-day I/sup 131/ by an atomic beam magnetic resonance experiment. The results were a = 575.903 plus or minus 0.007 Mc/sec, b = 578.866 plus or minus 0.075 Mc/sec. The zero-field hyperfine splittings computed from these values of a and b were DELTA nu (5,4) = 3292.99 plus or minus 0.09 Mc/sec, DELTA nu (4,3) = 2138.22 plus or minus 0.05 Mc/sec, DELTA nu (3,2) = 1314.24 plus or minus 0.07 Mc/sec. The nuclear magnetic dipole moment and nuclear electric quadrupole moment were calculated as mu /sub 131/ = 2.738 plus or minus 0.001 nm, Q/sub 131/ = --0.41 plus or minus 0.01 x 10/sup -24/ cm/sup 2/. The value of mu /s ub 131/ obtained differed slightly from that obtained by other workers, whereas the value of Q confirmed an earlier measurement made by a different method. (auth)
