The distributions of residual nuclei after annihilation of stopped antiprotons in 92M0, 95M0, 98M0 and 165H0 targets have been measured by means of the induced radioactivity. In the case of the 165H0 target the residual nucleus ~ 16Te was observed thus indicating that about 50 nucleons may be emitted after annihilation. The distributions have also been calculated with two versions of an intranuclear cascade model. The agreement between theory and experiment is satisfactory. The effects of heavy mesons in the annihilation process, of local reduction of the nuclear density during the intranuclear cascade and of multifragmentation are discussed.

Antiprotons have been stopped in a target of Ba(NO3) 2 . The induced radioactivity from antiproton annihilation in Ba was used to determine the distribution of residual nuclei. The results are compared with intranuclear cascade calculations. The agreement between theory and experiment is very good.

The yields of the atomic 4--*3 transitions in antiprotonic 14N, 16'17'180, 19F, and 2aNa were measured at the CERN antiproton facility, LEAR. From these, the widths F~p of the 4f levels were determined to be 136_+19meV (14N); 603_+22meV (160); 731 _+35 meV (~vO); 795+23 meV (xso); 2.79_+0.16 eV (19F); and 23.8_+7.4 eV (23Na).
