Measurements of the pp{yields}pp{pi}{sup 0} reaction at 310, 320, 340, 360, 400 and 425 MeV, and quasi-free pn{yields}pp{pi}{sup {minus}} production in pd collisions at 320 MeV have been carried out at the PROMICE/WASA facility at CELSIUS. The pp{yields}pp{pi}{sup 0} differential cross sections have been parameterized and used to deduce the poorly known {sigma}{sub 01} total cross section through the relation: {sigma}{sub 01}=2{sigma}(pn{yields}pp{pi}{sup {minus}}){minus}{sigma}(pp{yields}pp{pi}{sup 0}). Preliminary results show the {sigma}{sub 01} to be of the order of 50% of the {sigma}{sub 11} for the pp{pi}{sup {minus}} excess energy between 8 and 40 MeV.
