Study of thep¯p→n¯nreaction in the momentum range 480 to 728 MeV/c

Abstract

The total and differential $\overline{p}p$ charge-exchange cross sections were obtained at seven momenta in the range 480 to 728 MeV/c. The total cross sections are roughly consistent with other data. The momentum dependences of the Legendre coefficients $\frac{a_1}{a_0}$, $\frac{a_2}{a_0}$, and $\frac{a_3}{a_0}$ of the differential cross sections do not agree well with the predictions of the Bryan-Phillips model, unlike the case of elastic scattering.
