Abstract

The polarization of Ξ¯

{}^{+}

hyperons produced by 800-GeV/c protons in the inclusive reaction p+Be→Ξ¯

{}^{+}

+X has been measured. The average polarization of the Ξ¯

{}^{+}

, at a mean

x_{F}

=0.39 and

p_{t}

=0.76 GeV/c, is -0.097±0.012±0.009. The magnetic moment of the Ξ¯

{}^{+}

is 0.657±0.028±0.020 nuclear magneton.
