Antiprotonic potentials from global fits to the PS209 data

摘要

The experimental results for strong interaction effects in antiprotonic atoms by the PS209 collaboration consist of high quality data for several sequences of isotopes along the periodic table. Global analysis of these data in terms of a p-nucleus optical potential achieves good description of the data using a s-wave finite-range pN interaction. Equally good fits are also obtained with a poorly-defined zero-range potential containing a p-wave term.
