Abstract: Using 58 million decays obtained by BESII, a charged κ particle is observed in the analysis of the system recoiling against selected in . The mass and width values of the charged κ are obtained to be and for the Breit–Wigner parameters, and the pole position is determined to be . They are in good agreement with those of the neutral κ observed by the BES Collaboration. [Copyright &y& Elsevier]
