| English Abstract | By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the besiii detector operating at the bepcii collider, the decays of chi(c)(j) -> 4k(s)(0) (j = 0, 1, 2) are observed for the first time with statistical significances of 26.5 sigma, 5.9 sigma and 11.4 sigma, respectively. the product branching fractions of psi(3686) -> gamma chi(cj), chi(cj) -> 4k(s)(0 )are presented, and the branching fractions of chi(cj) -> 4k(s)(0) decays are determined to be b-chi c0 -> 4ks0 = (5.76 +/- 0.34 +/- 0.38) x 10(-4), b-chi c1 -> 4ks0 = (0.35 +/- 0.09 +/- 0.03) x 10(-4) and b-chi c2 -> 4ks0( )= (1.14 +/- 0.15 +/- 0.08) x 10(-4), where the first uncertainties are statistical and the second are systematic, respectively. |
