摘要：

The pionic deuterium 3P-1S x-ray transition was measured with a quartz crystal spectrometer in combination with a cyclotron trap and charge coupled device detectors. The strong interaction shift and total decay width of the 1S level are 1S shift=2.480.10 eV (repulsive), 1S width=1.020.21 eV, where the statistical and systematic errors were added linearly. They yield the total pionic deuterium S-wave scattering length: a-d=-0.0264(0.0011)+i0.0054(0.0011)m- 1. © 1995 The American Physical Society.
