英文摘要Using a data sample collected with the besiii detector operating at the bepcii storage ring at a center-of-mass energy of root s = 4.600 gev, we search for the production of e(+)e(-) -> phi chi(c0,1,2). a search is also performed for the charmonium-like state x(4140) in the radiative transition e(+)e(-) -> gamma x(4140) with x(4140) subsequently decaying into phi j/psi the processes e(+)e(-) -> phi chi(c1) and phi chi(c2) are observed for the first time, each with a statistical significance of more than 10 sigma, and the born cross sections are measured to be (4.2(-1.0)(+1.7) +/- 0.3) and (6.7(-1.7)(+3.4) +/- 0.5) pb, respectively, where the first uncertainties are statistical and the second systematic. no significant signals are observed for e(+)e(-) -> phi chi(c0) and e(+)e(-) -> gamma x(4140) and upper limits on the born cross sections at 90% c. l. are provided at root s = 4.600 gev.
