制备了两种由锡吸收剂和中子嬗变掺杂锗热敏电阻组成的热计，为核物理和亚核物理实验做了准备。两个检测器都完全解析了{sup 55}Mn的K{sub {alpha}1}和K{sub {alpha}2}行。该能量区域的反卷积FWHM分辨率在4.5 ~ 5.7thinspthinspeV之间，对于已公布的谱线的本征宽度和不对称性的不同值，是所有能量色散探测器在该能量区域获得的最佳分辨率。首次用能量色散光谱仪对K{sub {beta}{sup {prime}}}卫星峰进行了分析。{版权所有}{ital 1999} {ital美国物理学会}
Two bolometers composed of tin absorbers and neutron transmutation doped (NTD) Ge thermistors have been fabricated in preparation for experiments in nuclear and subnuclear physics. Both detectors fully resolve the two K{sub {alpha}1} and K{sub {alpha}2} lines of {sup 55}Mn . The deconvolved FWHM resolution in this energy region ranges from 4.5 to 5.7thinspthinspeV, for different published values of intrinsic widths and asymmetries of these lines, the best ever obtained at this energy with any energy dispersive detector. The K{sub {beta}{sup {prime}}} satellite peak is analyzed for the first time in a measurement with an energy dispersive spectrometer. {copyright} {ital 1999} {ital The American Physical Society}
