为检验活化法测量241Am的辐射俘获截面的可行性,在49-2反应堆的热柱上进行了241Am(n,γ)242Amg反应截面的试测量。样品采用电镀241Am样品,在辐照前测量了样品的α能谱,示于图1。样品活度在105Bq左右。参考截面采用197Au(n,γ)198Au反应截面。Am样品与Au样品放置在反应堆热柱上辐照约4d左右。辐照后的Am样品
To test the feasibility of the 241Am radiation capture cross section by activation method, a 241Am (n, γ) 242Amg reaction cross section was measured on a hot column of the 49-2 reactor. The sample was electroplated with a 241Am sample and the α spectrum of the sample was measured before irradiation, as shown in Figure 1. Sample activity is around 105Bq. The reference cross section uses 197Au (n, γ) 198Au reaction cross section. Am samples and Au samples were placed on the reactor hot column irradiated about 4d or so. Am samples after irradiation
