英文摘要	The open charm strong decay widths and certain ratio of branching fractions of a charmed strange baryon Xi(c)(2970) are calculated in a P-3(0) model. The results are compatible with the latest experimental data. The theoretical ratio of decay branching fractions R = B[Xi(c)(2970)(+) -> Xi c(2645)0 pi+]/B[Xi(c)(2970)+->Xi c'0 pi+]approximate to 1.0. The spin parity J(P) = 1/2(+) and 3/2(+) for different assignments are analyzed. From the results of our calculation,.co2970THORN can be interpreted as a 2S-wave state with JPoslTHORN = 1=2thorno0THORN. The distinctions between the 2S-wave n(rho)- and n(lambda)-excitation states and between states with s(l) = 0 and s(l) = 1 and between states with total spin 1= 2 and 3=2(s(l) = 1) are also discussed.
