SAMPLE     The irradiations of the samples were carried out within2286100100011 
           and without a cylindrical cadmium shield case. The     2286100100012 
           irradiations for eight samples for each element, which 2286100100013 
           are individually prepared from the fresh stocks, were  2286100100014 
           repeated four time, that is, a set of four, with and   2286100100015 
           without Cd-irradiation data for MnO(2), Ga(2)O(3),     2286100100016 
           As(2)O(3) are obtained. The samples were diluted to    2286100100017 
           minimize self-shielding during irradiation. For this,  2286100100018 
           the samples were mechanically mixed with finely grained2286100100019 
           Al(2)O(3) powder by 98.6-96%, since Al-27 isotope has  2286100100020 
           low neutron absorption cross section.                  2286100100021 
           The irradiation times for the (n,gamma) reactions of   2286100100022 
           Mn-55, Ga-71, As-75 were chosen for a period of        2286100100023 
           3-6 half-lives, yielding enough activity to be measured2286100100024 
            in gamma-ray counting system.                         2286100100025 
ADD-RES    (COMP) The results are discussed and compared with     2286100100026 
           previous measurements and the evaluated data in        2286100100027
