Among the more attractive radionuclides for lung and liver imaging in children and adults, particularly in cardiovascular examinations, is {sup 178}Ta. This radionuclide is readily available from the radionuclide generator {sup 178}W EC (T{sub 1/2} = 21.7d) {sup 178}Ta EC,{beta}{sup +}(T{sub 1/2} = 9.3min) {sup 178}Hf (stable). The long lived {sup 178}W (T{sub 1/2} = 21.7d) decay entirely by EC to 9.3 m {sup 178}Ta daughter without feeding the high spin isomer (T{sub 1/2} = 2.2 h) in {sup 178}Ta. The short lived {sup 178}Ta then decays to stable {sup 178}Hf, 98.2% by EC and 1.1% by {beta}{sup +} emission. In this paper, the authors report the excitation function for the {sup 181}Ta(p,4n){sup 178}W reaction in the proton energy range of 28.8-71.8 MeV.
