Exclusive measurements of the reaction pp -> dpi+pi0 have been carried out at T_p = 1.1 GeV at the CELSIUS storage ring using the WASA detector. The isovector pi+pi0 channel exhibits no enhancement at low invariant pipi masses, i. e. no ABC effect. The differential distributions are in agreement with the conventional t-channel Delta-Delta excitation process, which also accounts for the observed energy dependence of the total cross section. This is an update of a previously published version -- see important note at the end of the article.

Table 1

Updated total cross section for the reaction P P --> DEUT PI+ PI0, from the erratum.

Table 2

Angular distribution of the PI0 in the CM system for the process P P --> DEUT PI+ PI0. As described in the erratum, these values should be multiplied by a factor of 2.3.

Table 3

Angular distribution of the deuterium in the CM system for the process P P --> DEUT PI+ PI0. As described in the erratum, these values should be multiplied by a factor of 2.3.
