| Abstract: | 45Ti is a positron emitter radioisotope with weak gamma radiation. As its half-life (T1/2 = 3.08 h) is in the same range that of 18F and comparable with 43,44Sc, it is a good metallic alternative for radio-labelling of different proteins and other applications in nuclear medicine. The activation cross section and yield for possible production routes have been measured by several authors for decades, but probably because of its weak gamma-line and the different measurement techniques the results are very different and confusing. In the present work proton induced reactions are investigated to gain reliable activation cross section for the 45Ti production from naturally monoisotopic scandium. The study also resulted in production cross sections of 44g,44m,43Sc and 44Ti as side products. The results are compared with the previous literature data and with the results of the latest TENDL version. |
