摘要：

We present data obtained at the ISR, on the determination of the ratio R = γ π0 at s = 30.6 GeV and we compare the results with our previous measurement at s = 53.2 GeV. The ratio R = γ π0 integrated over the interval 0.1 ≤ χT ≤ 0.2 is (1.6 ± 0.5) × 10-2 and we obtain an indication of a universal χT dependence. © 1979.
