Nonradiative Absorption of Positive Pions by Deuterons at 118 Mev

Abstract

The reaction ${\pi }^{+}+d\to p+p$ was studied at a center-of-mass pion energy of 118±2 Mev, using scintillation counters and a liquid deuterium target. The angular distribution was given by $\frac{d\sigma }{d\Omega }\propto A+{cos}^2\theta$, with $A=0.216\mathrm{}\pm 0.033$, while the total cross section was 12.09±0.93 mb. The total cross section for the inverse pion production reaction was calculated from detailed balancing as 3.10±0.24 mb. These results are compared with other work.
