Observation of Nuclear Spin Waves in Spin-Polarized Atomic Hydrogen Gas Academic Article uri icon

abstract

  • We have observed narrow, distinct resonances in the NMR spectrum of dilute spinpolarized atomic hydrogen gas (n1016 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, 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.
