We report the measurement of beam-target double spin asymmetries (ALT) in the inclusive production of identified hadrons, e⃗  + 3He↑→h+X, using a longitudinally polarized 5.9-GeV electron beam and a transversely polarized He3 target. Hadrons (π±,K±, and proton) were detected at 16∘ with an average momentum ⟨Ph⟩=2.35 GeV/c and a transverse momentum (pT) coverage from 0.60 to 0.68 GeV/c. Asymmetries from the 3He target were observed to be nonzero for π± production when the target was polarized transversely in the horizontal plane. The π+ and π− asymmetries have opposite signs, analogous to the behavior of ALT in semi-inclusive deep-inelastic scattering.
