摘要：

Quantitative activation energy data on the v= 5 2 even-denominator fractional quantum Hall effect are reported. The energy gap is found to drop linearly with total magnetic field in tilted fields with a slope roughly consistent with the bare g-factor for electrons in GaAs. These data further support the suggestion that the v= 5 2ground state is spin unpolarized. © 1990.
