Asymmetries, A{sub y}, for the ({pi}{sup {minus}},{pi}{sup 0}) reaction on polarized {sup 3}He were measured using the pion beam of the P3W channel at LAMPF. The {pi}{sup 0} were detected with the new Neutral Meson Spectrometer (NMS) in coincidence with recoiling tritons. The recoil detector consisted of scintillation-counter telescopes and a wire chamber that provided energy-loss and direction information, respectively. The polarized gaseous {sup 3}He target developed at TRIUMF was modified and run with the use of two diode lasers. Polarizations were typically 50%. The A{sub y} taken at T{sub {pi}} = 200 MeV between 60 and 105{degrees} were found to be strongly angle-dependent. The results will be compared with the theoretical predictions.
