We show that the symmetric quark model calculation of charmed baryon pair creation in e+e--annihilation has an incorrect threshold structure. The cC-pair creation model posessPs the correct s-wave threshold behaviour, if the cc-pair and diquark pair are created in orbital s-waves. We show that the two models become identical for a specific orbital configuration and discuss implications for the relative production rates of 1\:.~: ~c~: ~cf.; +EtZ-c: 2:.;"~ +doi:10.1016/0370-2693(77)90443-9 fatcat:pueqrz267bdvjh3qjttfwrsjfa
