A0318 1 12 COMMENT /By authors/ In the case of 30P, which only gives A0318 1 13 rise to annihilation radiation, it was really 2,5 min A0318 1 14 30P and not 2.03 min O-15. Therefore, besides gamma- A0318 1 15 ray spectroscopy, counting of positrons above 2.0 MeV A0318 1 16 /i.e. above the cut-off energy of the positrons from A0318 1 17 O-15/ was also applied. Both the counting methods A0318 1 18 gave similar results, confirming thereby that the A0318 1 19 activity under investigation was pure 30P.
