Fig. 1: a, the ratio of real and imaginary parts of the various ampli-
tudes discussed in the mathematical example of Section II. The
subtraction constant c is chosen so that for v < A, 'I , 'I.
Fig. 2: -p total cross sections and fit (10). Errors plotted are the
sum of the statistical and the systematic. The statistical
errors of Allaby et al. are also indicated. The errors of
Citron et al. are mainly systematic, and only representative
data points of this group have been included.
Fig. 3: Predicted a(ip) = Re A(nlp)/Im A( h) and experimental data
of Foley et al.) I and II refer to the choice of high-energy
cross sections. (See Fig. 2.) c is the subtraction constant.
Fig. 4: Forward differential irN charge exchange cross sections predicted
assuming exact I spin conservation, and data of Mannelli et al.9)
Fig. 5: Blow-up of Fig. 4. The discrepancy between the fit and the data
is an indication of the amount of I-spin violating electromagnetic
effect. On the basis of this deviation, we conclude
20E" < 0.5 mb.
Fig. 8: a(Krp) = Re A(K-p)/Im A(K]4) and experimental limits
deduced from the forward elastic differential cross sections.10,11)
The sign of (K+p) was determined from the dispersion relations.
