Direct flow separation strategy, to isolate no-carrier-added 90Nb from irradiated Mo or Zr targets

Autor: Frank Roesch, D.V. Filosofov, Ayagoz Baimukhanova, Jakhongir Dadakhanov, Valery Radchenko, Atanaska P. Marinova, D. V. Karaivanov

90Nb has an intermediate half-life of 14.6 h, a high positron branching of 53% and optimal β + emission energy of only E mean 0.35 MeV per decay. These favorable characteristics suggest it may be a potential candidate for application in immuno-PET.
