Description
We present accurate results for the energy levels of antiprotonic helium atoms with the relativistic and QED corrections of order α4mc2 taken into account. These results reduce the discrepancy between theory and experiment to about 5 endash 10ppm and rigorously confirm Condo close-quote s model of metastability for the long-lived fraction of antiprotonic helium. The present level of precision enables the unambiguous ascription of quantum numbers to all of the transition lines observed so far. copyright 1997 The American Physical Society
