Abstract
Metastable states in the antiprotonic helium isotopic system (p) over bar(3)He(+) were studied. Vibrational energy levels for the total angu lar momentum J = 30-38 were calculated using a three-dimensional finit e element method. The dipole transition probability formalism was used to calculate the radiative decay rates of experimentally relevant tra nsitions. Relativistic and QED corrections were calculated. Isotope ef fects were studied based on a comparison of our presented data with re cently published results for the (p) over bar(4)He(+) system.
