【 摘 要 】

We present a review of BaBar results on e(sup +)e(sup -) annihilations into exculsive hadronic final states using the initial state radiation technique. Cross sections over the (radical)s range from threshold to 4.5 GeV, with very small point-to-point systematic errors, are presented for the 3(pi), 2(pi)(sup +)(pi)(sup -)), 3(pi)(sup +)(pi)(sup -)), 2((pi)(sup +)(pi)(sup -)) 2(pi)(sup O), K(sup +)K(sup -)(pi)(sup +)(sup -), 2(K(sup +)K(sup -)) and p(bar p) final states. The proton form factor and the ratio of its electric and magnetic components are also presented.
