Abstract

We present data on the inclusive scattering of polarized electrons from a polarized 3He target at energies from 0.862 to 5.06 GeV, obtained at a scattering angle of 15.5 degrees. Our data include measurements from the quasielastic peak, through the nucleon resonance region, and beyond, and were used to determine the virtual photon cross-section difference sigma(1/2)-sigma(3/2). We extract the extended Gerasimov-Drell-Hearn integral for the neutron in the range of four-momentum transfer squared Q2 of 0.1-0.9 GeV2.

摘要

我们展示了在15.5度散射角下，能量范围为0.862至5.06 GeV时，极化电子与极化3He靶的包容性散射数据。我们的数据包括从准弹性峰到核子共振区及以外的测量结果，并用于确定虚光子截面差sigma(1/2)-sigma(3/2)。我们在四动量转移平方Q2为0.1-0.9 GeV2的范围内提取了中子的扩展Gerasimov-Drell-Hearn积分。
