摘要：
This work reports experimental 70Ge(d,n)71As cross sections producing Arsenic-71 (t1/2 = 65.3 h, 28% beta+), a potentially useful diagnostic radionuclide. Target stacks containing two natGe foils, a natNi monitor foil, and an Al degrader were irradiated with 5.5-10 MeV deuterons using an FN Tandem Van de Graaff accelerator. 71As and 61Cu, 56Co, and 58Co (from natNi(d,x)) were quantified in the foils by high purity germanium gamma spectrometry. The measured cross sections are larger than previously reported and suitable for producing preclinical quantities of diagnostic radiopharmaceuticals.
