We present accurate results for the energy levels of antiprotonic helium atoms with the relativistic and QED corrections of order {alpha}{sup 4}mc{sup 2} 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} {ital 1997} {ital The American Physical Society}
