Abstract
The cross sections for image, image and image production by image annihilation at the center-of-mass energy image have been directly measured with the BES-II detector at the BEPC collider. The measurement of the cross sections is made by analyzing both the singly tagged D events and the doubly tagged image events from the data sample of about 17.3 pb−1 collected at image. The observed cross sections are image, image and image, which correspond to the tree level cross sections to be image, image and image, respectively.
