Abstract

The x-ray cascade from antiprotonic atoms was studied for 122Te, 124Te, 126Te, 128Te, and 130Te. Widths and shifts due to the strong interaction were deduced for several levels. The E2 nuclear resonance effect was observed in all investigated nuclei. In 130Te the E2 resonance allowed to determine level widths and shifts of the LS-split deeply bound (n, l) = (6, 5) state, otherwise unobservable. The measured level widths and shifts, corrected for the E2-resonance effect, were used to investigate the nucleon density in the nuclear periphery. The deduced neutron distributions are compared with results of the previously introduced radiochemical method and with Hartree-Fock-Bogoliubov model calculations.
