Evaluation of production cross-sections for ~(61)Cu non-standard PET radionuclide via light-ion-induced nuclear reactions on Co, Ni, Zn targets

摘要

Production cross-sections of Cu-61, a promising radionuclide for PET imaging applications, were evaluated for the light-ion-induced nuclear reactions on Co, Ni, Zn targets. Simultaneous Evaluation on KALMAN (SOK) code combined with least squares concept was used to obtain the evaluated data together with covariances. The various production routes of Cu-61 were compared, and recommended excitation functions were derived using a well-defined statistical procedure. The evaluated data were also compared with the predictions of the nuclear reaction model codes TALYS and EMPIRE, and found a partial agreement among them. This study indicates that the Ni-60(d,n)Cu-61 reaction is the method of choice for Cu-61 production; however, the Ni-58(alpha,p)Cu-61 and Co-59 (alpha,2n)Cu-61 reactions also appears to have great potential.
