| 英文摘要 | We present measurements of the charmonium state h(c) (p-1(1)) made with 106 x 10(6) psi' events collected by besiii at bepcii. clear signals are observed for psi' -> pi(0)h(c) with and without the subsequent radiative decay h(c) -> gamma eta(c). first measurements of the absolute branching ratios b(psi' -> pi(0)h(c)) = (8.4 +/- 1.3 +/- 1.0 x 10(-4) and b(h(c) -> gamma eta(c)) = (54.3 +/- 6.7 +/- 5.2)% are presented. a statistics-limited determination of the previously unmeasured h(c) width leads to an upper limit gamma(h(c)) < 1.44 mev (90% confidence). measurements of m(h(c)) = 3525.40 +/- 0.13 +/- 0.18 mev/c(2) and b(psi' -> pi(0)h(c)) x b(h(c) -> gamma eta(c)) = (4.58 +/- 0.40 +/- 0.50) x 10(-4) are consistent with previous results. |
