    "abstract": "We study the electromagnetic transitions of the Roper N(1440) resonance. Our\nresults, when combined with the previously obtained for the mass and the pionic\nstrong decay widths of the Roper, show that within a non-relativistic\nconstituent quark model scheme, a comprehensible understanding of the Roper\nphenomenology can be achieved. They also seem to support the view of the Roper\nas a radial excitation of the nucleon, though more experimental data are needed\nto reach a definitive conclusion.",
