Abstract

The wavelengths and the natural line widths of the 3d-2p transitions in the pionic atoms of 12C, 16O, 18O, 24Mg, 26Mg, 28Si and 30Si have been measured at SIN with a bent-crystal spectrometer. The precision reached in the transition wavelengths ranges from 4 to 18 ppm, and in the widths from 2 to 14%.
