Exclusive measurements of the two-pion production channel p p -> p p pi+ pi- have been carried out near threshold at CELSIUS with the PROMICE/WASA detector. They reveal p p -> p p*(1440) -> p p sigma -> p p (pi+ pi-)I=l=0 as the dominant process at these energies, however, the data exhibit also significant contributions from p*(1440) -> Delta pi -> p (pi+ pi-)I=l=0 . From the observed interference of this routes their relative branching ratio is derived.
