These logarithmic terms are not present in a more physical approximation than the ladder series. If this were not enough, Nakanishi has shown that certain solutions have a negative norm! They are called "ghosts," and it is unclear whether they result from the inadequacy of the approximation or from a deeper inconsistency of the theory. The previous study may be generalized to the inhomogeneous equation for the amplitude, in particular to highenergy behavior in the crossed channel (corresponding to the exchanged particles). It is possible to find a Regge behavior sa(t) with a computable trajectory function a(t).

Various attempts have been made to introduce an effective potential (or quasipotential) approximation to reduce the number of degrees of freedom of the relativistic boundstate problem, in particular the troublesome relative time. Even though they lead to interesting practical results, they mutilate one way or another the exact theory and generally introduce spurious singularities. 103 HYPERFINE SPLITTING IN POSITRONIUM
It should not be concluded that relativistic weak binding corrections cannot be obtained for twobody systems that agree with experiment. On the contrary, the positronium states give an example of a successful agreement. This will serve to illustrate the theory. To be completely fair, we should admit that accurate predictions require some artistic gifts from the practitioner. As yet no systematic method has been devised to obtain the corrections in a completely satisfactory way. We quote here some of the significant results and refer to Secs. 23 and 52 for preliminary investigations. Even though in the study of positronium we restrict ourselves to an almost pure electromagnetic system, some of the methods are useful in other instances such as models of quark bound states of hadrons. The energy difference between the higher triplet (ortho) and lower singlet (para) ground states of positronium, denoted respectively 13 S1 and 11 So (in the spectroscopic notation n 2S + 1 L J ), has now been measured with great accuracy. The values quoted for this hyperfine splitting fiE ts are fiE ts = 2.033870 (16) x 105 MHz

The interval is sometimes also called the fine structure of positronium. Recently Mills, Berko, and Canter have also measured the spacing between n = 2 triplet excited levels (1080) We recall that all these states are unstable. The groundstate radiative width has already been discussed to lowest order (Sec. 52). We may understand the magnitude and sign of the singlettriplet splitting in positronium by noticing that it corresponds to the sum of two effects. The magnetic interaction is given by the Fermi estimate discussed in the context of the hydrogen atom (Sec. 232). In terms of the electronpositron parameters with gyro magnetic factors equal to 2, it reads where [((!o [2 is the square of the nonrelativistic wave function at the origin for a system of two equalmass particles [((!O[2 = (mrx)3/8n. We have also to deal with a new effect corresponding to the annihilation channel, as was mentioned in the early discussion of electronpositron scattering (Sec. 613). If we restrict ourselves to the lowestorder effect it corresponds to the onephoton channel contributing an swave interaction energy of order rx to the triplet state only because of its odd charge conjugation. The desired energy shift may be computed from an effective potential identified with the corresponding Tmatrix element at the threshold (S = I + iT) multiplied by [((!O[2 From Chap. 6, the scattering amplitude at the threshold is u(2)yV u(1)u(1)Y v v(2) (2m)2 We have been careful about the signs and u(v) denotes the electron (positron) spinor at the threshold u(l) = (~,) u(l) = (xI. 0) v(2) = CuT(2) = (
