*In the ISOLDE Yield Database the beam intensities for isotopes of the elements measured at ISOLDE PSB (PS Booster with 1.0 or 1.4 GeV protons) are presented. For isotopes where no new yields are listed yet from the PSB, one can get an idea from looking at the available SC yields (0.6 GeV protons).
