Abstract

The activation energy measured in transport experiments in the fractional Hall regime corresponds to the energy required to create a far separated particle hole pair. We calculate, for several fractional quantum Hall states, the energy gaps for the excitation in which the excited composite fermion reverses its spin-quantum number. Our results indicate that such spin-reversed excitations may be relevant in experimentally accessible regimes.
