Abstract

We present data on collective flow of neutrons in collisons of ${}^{197}{Au}$ + ${}^{197}{Au}$ at 400 MeV/nucleon. The azimuthal distribution about the beam axis is investigated with respect to the reaction plane as determined from light charged particles. The ‘‘squeezeout’’ of neutrons, perpendicular to the reaction plane, is observed for the first time. Quantitative agreement to a high level of accuracy is found between the behavior of neutrons and hydrogen ions.
