“…Measurements of the four-particle yield in the reaction pp--*ppn-n + at T~ab=730 MeV, i.e. at 6T,~20 MeV, give total cross sections of 8(5)Ixb [16] and 30(10)gb [17], respectively. Aside from the fact that both measurements do not agree well within their uncertainties, these results mean that the total cross section for 2n-production is substantially larger than the predicted cross section for d' production.…”
