| Abstract: | Initial distributions of metastable antiprotonic (4)He and (3)He atoms over principal (n) and angular momentum (l) quantum numbers have been deduced using laser spectroscopy experiments. The regions n = 37-40 and n = 35-38 in the two atoms account for almost all of the observed fractions (3.0 +/- 0.1)% and (2.4 +/- 0.1)%] of antiprotons captured into metastable states. |
