Svedberg Lab-Uppsala. Measurement of the cross section for the reaction P DEUT --& gt; P DEUT ETA at the CELSIUS storage ring. The data cover 5 proton kinetic energies from 0.927 to 1.096 GeV. ; Other ; Total cross section as a function of the incident proton kinetic energy and the excess energy Q given by SQRT(S)-M(P)-M(D)-M(ETA).
