The multi-differential data were measured by the HADES Collaboration. Exclusive channels with one pion in the final state ($np\pi^+$ and $pp\pi^0$ were put to extended studies based on various observables in the framework of a one-pion exchange model and with solutions obtained within the framework of a partial wave analysis (PWA) of the Bonn-Gatchina group. The results of the PWA confirm the dominant contribution of the $\Delta(1232)$, yet with a sizable impact of the $N(1440)$ and non-resonant partial waves.engjournal article2019-02-04
