摘要：

A graphite target was bombarded with 1.5 MeV deuterons, producing the isotope (13)N, which is a positron emitter. Using the activated material a slow positron beam with an intensity of 0.7 (0.14) x 10(5) s(-1) was produced. A (saturated) (13)N yield of 63 (11) MBq/muA was observed, with 1.5 MeV deuterons, which is consistent with previous calculations and experiments. Our results show that, with the method we outline, positron beams with an average intensity of up to 1 x 10(8) s(-1) may be produced. (C) 2002 Elsevier Science B.V. All rights reserved.
