Abstract
Antiprotonic x-ray spectra of , , , , and have been measured with Ge detectors. The nuclear-resonance effect was observed for the first time in atoms, yielding information on the "hidden" , level of the -molybdenum atom. Strong interaction widths and shifts affecting the 7 → 6 transition were determined and the effective -nucleon scattering length was deduced. A unique strong-coupling effect was established in .
