    "abstract": "A new mechanism for the pp --\u003e pp pi0 reaction close to threshold is\nsuggested coming from the isoscalar excitation of the Roper and its decay into\nN(pi pi)S-wave, with one of the pi0 emitted and the other one reabsorbed on the\nsecond nucleon. The mechanism can lead to important interference with other\nmechanisms and, together with experiment, serves to exclude large ranges of the\n2pi N* decay parameters allowed by the N* partial decay widths.",
