We report the measurement of beam-target double spin asymmetries (A_LT) in the inclusive production of identified hadrons, ^→e + ³He^↑ → h + X, using a longitudinally polarized 5.9-GeV electron beam and a transversely polarized ³He target. Hadrons (π^±, K^±, and proton) were detected at 16 ° with an average momentum ( P_h ) = 2.35 GeV/c and a transverse momentum (p_T) coverage from 0.60 to 0.68 GeV/c. Asymmetries from the He-3 target were observed to be nonzero for π^± production when the target was polarized …
