COMMENT /By authors/ In the case of 30P, which only gives A031800100013
rise to annihilation radiation, it was really 2,5 min A031800100014
30P and not 2.03 min O-15. Therefore, besides gamma- A031800100015
ray spectroscopy, counting of positrons above 2.0 MeV A031800100016
/i.e. above the cut-off energy of the positrons from A031800100017
O-15/ was also applied. Both the counting methods A031800100018
gave similar results, confirming thereby that the A031800100019
activity under investigation was pure 30P. A031800100020
