Abstract

We present a measurement of the spin-dependent cross sections for the ³\stackrel\ensuremath→He(\stackrel\ensuremath→e,e^\ensuremath')X reaction in the quasielastic and resonance regions at a four-momentum transfer 0.1\ensuremath≤Q²\ensuremath≤0.9 GeV². The spin-structure functions have been extracted and used to evaluate the nuclear Burkhardt-Cottingham and extended Gerasimov-Drell-Hearn sum rules for the first time. The data are also compared to an impulse approximation calculation and an exact three-body Faddeev calculation in the quasielastic region.
