Abstract

We report on the experimental results obtained at the ISR for the η particle production at 90° and √s = 30.6 and 53.2 GeV. We determine the invariant cross section and the pt distribution in the interval 1 ⩽ pt ⩽ 5 GeV/c. We find that the pt distribution has the same shape of the π0 production and differ from it by a constant factor R90° = 0.5 ± 0.07.
