Abstract
Exclusive measurements of the reactions pdâHe3Ï+Ïâ and pdâHe3Ï0Ï0 have been carried out at Tp=0.893GeV at the CELSIUS storage ring using the WASA detector. The Ï+Ïâ channel evidences a pronounced enhancement at low invariant ÏÏ masses-as anticipated from previous inclusive measurements of the ABC effect. This enhancement is seen to be even much larger in the isoscalar Ï0Ï0 channel. The differential distributions prove this enhancement to be of scalar-isoscalar nature. ÎÎ calculations give a good description of the data, if a boundstate condition is imposed for the intermediate ÎÎ system.
