The Moment

Atomic beam magnetic resonance has been used to study the 41-s isomeric state of 109Ag. The measured nuclear spin is 7/2 and the hyperfine interaction constant in the 2S1/2 electronic state is found to be 9550 ± 100 MHz. The special nature of the data also provides a direct evaluation of the nuclear magnetic moment, μI(corr.) = +4.27 ± 0.13 nuclear magnetons. The accuracy, however, is limited by the possibility of power shifts in the observed resonances and the error quoted is an estimate of this uncertainty. The moment is in closest agreement with theory if one assumes the state is the result of the coupling of three quasi-particles.

The hyperfine structure of the 4.5-hour metastable state of indium-115 has been studied by the method of atomic beam magnetic resonance. The values found for the hyperfine interaction constants are −903.5 ± 1.1 and −95.973 ± 0.010 Mc/sec in the 2P1/2 and 2P3/2 electronic states respectively. Neglecting a possible hyperfine anomaly, these correspond to a nuclear magnetic moment for In115m of −0.24371 ± 0.00005 nuclear magnetons. The construction of the atomic beam apparatus, recently completed at McMaster University, is also described.

By the method of nuclear magnetic resonance, the magnetic moment of Sc45 (without diamagnetic correction) is found to be 4.74916 ± 0.00012. The correction is +0.00717 with unknown and possibly large error. The equipment designed to search for magnetic resonance by varying the field of the magnet is described, with special emphasis on the magnet current regulator.

The hyperfine structure of 1.9-hour 117mIn has been investigated using atomic magnetic resonance. In the 2P1/2 and 2P3/2 electronic states, the magnetic dipole interaction constants are[Formula: see text]If the possibility of a hyperfine anomaly is neglected, the nuclear magnetic moment of 117mIn is −0.251 46 ± 0.000 03 nuclear magnetons. Thus the nucleus follows the trend shown by other 2p1/2 proton nuclei, namely that the addition of a neutron pair always reduces the deviation from the Schmidt value.

The structure of the resonance lines of the arc spectrum of aluminium was investigated by the method of absorption in an atomic beam, and the structure of certain other lines of aluminium, emitted by a liquid-air-cooled hollow cathode tube, was also investigated. The nuclear spin of aluminium was thus shown to be 9/2 and the magnetic moment about 4·0 nuclear magnetons. A note (Jackson and Kuhn 1937 a ) containing these results was published elsewhere. The light source and the spectroscope The arc spectrum of aluminium possesses two groups of resonance lines, 3 2 P 3/2 , ½ -4S ½ (3962 A, 3944 A) and 3 2 P 3/2 , ½ -3 2 D 5/2 , 3/2 (3092·7 A, 3092·8 A, 3082 A).

This chapter is devoted to one of key phenomena in the field of spin physics, namely, resonant absorption of electromagnetic waves under conditions where the Zeeman splitting of spin levels in magnetic field is equal to photon energy. This method is particularly important for identification of nuclear spin effects, because resonance spectra provide fingerprints of different involved spin species and make it possible to distinguish different nuclear isotopes. As discussed in this chapter the nuclear magnetic resonance provides also an access to local magnetic fields acting on nuclear spins. These fields are caused by the magnetic interactions between the nuclei and by the quadrupole splittings of nuclear spin states in anisotropic crystalline environment. Manifestations of spin resonance in optical responses of semiconductors–that is, optically detected magnetic resonance–are discussed.
