We present a measurement of the spin-dependent cross sections for the polarized 3He(polarized e;e')X reaction in the quasielastic and resonance regions at a four-momentum transfer 0.1 < Q2 < 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.

Abstract
We present a measurement of the spin-dependent cross sections for the polarized 3He(polarized e;e')X reaction in the quasielastic and resonance regions at a four-momentum transfer 0.1 < Q2 < 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
