We study the process \u3b3\u3b3\u2192J/\u3c8\u3c9 using a data sample of 519.2fb -1 recorded by the BABAR detector at SLAC at the PEP-II asymmetric-energy e +e - collider at center-of-mass energies near the \u3a5(nS) (n=2,3,4) resonances. We confirm the existence of the charmoniumlike resonance X(3915) decaying to J/\u3c8\u3c9 with a significance of 7.6 standard deviations, including systematic uncertainties, and measure its mass (3919.4\ub12.2\ub11.6)MeV/c2 and width (13\ub16\ub13)MeV, where the first uncertainty is statistical and the second systematic. A spin-parity analysis supports the assignment JP=0 + and therefore the identification of the signal as due to the \u3c7 c0(2P) resonance. In this hypothesis we determine the product betwe...
