    abstract = "The directed and elliptic flow of protons and charged pions has been
observed from the semicentral collisions of a 158 GeV/nucleon Ph beam
with a Pb target. The rapidity and transverse momentum dependence of the
flow has been measured. The directed flow of the pions is opposite to
that of the protons but both exhibit negative flow at low p(t). The
elliptic flow of both is fairly independent of rapidity but rises with
p(t)."
