Positronium spectroscopy is of continuing interest as a high-precision test of our understanding of binding in QFT. Spectroscopic studies of low-lying states (n= 1 hyperfine splitting, n= 2 fine structure, and the 1S—2S interval) have reached a precision of order 1MHz, and ongoing experimental efforts give the promise of improved results. Theoretical calculations of positronium energies at order mα 6∼ 18.7 MHz are complete, but only partial results are known at order mα 7∼ 0.14 MHz. We report on the status of the positronium energy calculations and give some details of the methods employed.
