AbstractAbstract
[en] The ratio of positive pion photoproduction cross-sections on 6Li and protons was measured near the threshold. The result is considerably lower than the existing theoretical predictions

AbstractAbstract
[en] In an improved experiment, the new measurement of the 6Li π+ photoproduction near threshold has yielded the value a(6Li→6He)/a(proton)=0.098+-0.004 in reasonable agreement with current predictions. Deuterium yields have been measured from 1 to 5MeV above threshold; this experiment is a test case of the overall understanding of the π+ photoproduction process on nuclei near threshold

Dans une experience amelioree de remesure de la photoproduction 6Liπ+ pres du seuil on a obtenu la valeur a(6Li→6He)/a(proton)=0,098+-0,004 en accord raisonnable avec les predictions courantes. Pour le deuterium la mesure a ete faite entre 1 et 5MeV au-dessus du seuil; cette experience est un test de la comprehension totale du processus de photoproduction π+ sur les noyaux au voisinage du seuilOriginal Title
