Abstract

We present the first precision measurement of the spin-dependent asymmetry in the threshold region of ³\stackrel\ensuremath→He(\stackrel\ensuremath→e,e^\ensuremath') at Q² values of 0.1 and 0.2(GeV/c)². The agreement between the data and nonrelativistic Faddeev calculations which include both final-state interactions and meson-exchange current effects is very good at Q²\phantom\rule0ex0ex=\phantom\rule0ex0ex0.1(GeV/c)², while a small discrepancy at Q²\phantom\rule0ex0ex=\phantom\rule0ex0ex0.2(GeV/c)² is observed.
