  Preliminary results of the strong interaction shift and width in pionic
hydrogen ($\pi H$) using an X-ray spectrometer with spherically bent crystals
and CCDs as X-ray detector are presented. In the experiment at the Paul
Scherrer Institute three different $(np\to 1s)$ transitions in $\pi H$ were
measured. Moreover the pion mass measurement using the $(5 \to 4)$ transitions
in pionic nitrogen and muonic oxygen is presented
