Each of the samples of Mn-O2 2289100100021 and Dy2-O3 was mixed independently with a sufficient 2289100100022 amount of Al(2)O(3) powder. 2289100100023 COMMENT *By authors*.The irradiation times for the (n,gamma) 2289100100024 reactions of Mn-55 and Dy-164 were chosen for a period 2289100100025 of three to six half-lives, yielding enough activity 2289100100026 to be measured in a gamma-ray
