Phys. Rev. C 60, 025204 (1999) [6 pages]Isoscalar Roper (N1440*) excitation in the pp⃗ppπ0 reaction close to thresholdReceived 8 September 1998; published 21 July 1999 A new mechanism for the pp⃗ppπ0 reaction close to threshold is suggested coming from the isoscalar excitation of the Roper and its decay into N(ππ)s-wave, with one of the π0 emitted and the other one reabsorbed on the second nucleon. We show that this new mechanism can lead to important interference with other mechanisms suggested so far. © 1999 The American Physical Society URL:
