摘要：

We consider the contribution of radially excited 2(3)P(1,2) states to psi' production at the Tevatron energy. Production of these states Dia the conventional gluon fusion mechanism and via gluon and charm quark fragmentation processes is considered. With optimistic estimates of the decay branching fractions of these 2(3)P(1,2) states into psi', it is possible to account for the large psi' production cross-section observed by the CDF experiment.
