Significant isotopic deviations over the analytical accuracy were not observed in (Sm-149)-(Sm-150) and (Gd-157)-(Gd-158) of the two samples. The estimated neutron fluences of 1F and 2F were (0 +/- 2.2) x 10(exp 15) and (0.8 +/- 3.1) x 10(exp 15) n/cm(sup 2), respectively., 資料番号: SA0200003000}, pages = {19--24}, title = {Sm and Gd isotopic measurements in test samples for the MUSES-C mission}, volume = {16}, year = {2003} }
