Phys. Rev. Lett. 52, 1508–1511 (1984)Observation of Nuclear Spin Waves in Spin-Polarized Atomic Hydrogen GasSee Also: Erratum Received 24 January 1984; published in the issue dated 23 April 1984 We have observed narrow, distinct resonances in the NMR spectrum of dilute spinpolarized atomic hydrogen gas (n∼1016 atoms/cm3). The dependence of the observed spectra on temperature, density, polarization, and magnetic field gradient is consistent with theoretical predictions for spin-wave excitations damped by diffusion. We have measured the parameter μ, which is a measure of the importance of exchange effects in spin-transport processes, and the diffusion coefficient D0, both of which are in reasonable agreement with theory. © 1984 The American Physical Society URL:
