• 中文摘要： 經由非彈性散射方程（Inelastic scattering function)的測量，60 KeV光子被銅原子非彈性散射及660 KeV光子被金原子非彈性散射已被研討。高鑑別率的矽（鋰）X光偵測器被用來偵測60 KeV光子被銅原子散射後的能譜，散射的範圍由 (方程式無法摘錄) 。而660 KeV光子被金原子教射的能譜則以1"×1"MaI（TI)來偵測，其散射範圍為x=13.8到48.4之間。兩者均以碳靶為參考靶。我們測得的非彈性散射方程與以非相對論Hartree-Fock計算的結果相比對，發現我們的測量值要比計算值為小。
• 英文摘要： The inelastic scattering of incident photon energy of 60 KeV by Cu atoms has been studied throughthe measurements of its incoherent scattering function S(x, Z). A high resolution Si(Li) Xray detector wasused to detect the inelastically scattered photons. The range of x is from 1.04 to 2.40. We also used a 1”×1”Nal(T1) detector to measure the incoherent scattering function of the 660 KeV photon scattered by Auatoms. The range of x is from 13.8 to 48.4. Both of our experimental values of S(x, Z) are somewhatsmaller than the results tabulated by Hubbell et al. based on the non-relativistic Hartree-Fock calculations.
