摘要: 本文从理论上研究121Sb的穆斯堡尔同质异能移,从能带理论的观点研究固体电子结构,提出压缩原子模型,考虑固体中原子体积的有限性,并在此基础上计算核内电子电荷密度和121Sb的穆斯堡尔定标常数。
Abstract: The M?ssbauer isomer shifts of 121Sb have been evaluated in the present paper, in which the electronic structure of the atoms bonded together was considered by using band-structure calculations. The finite size of atoms in the solid was also taken into account. Based on the above considerations the calibration constants for 121Sb M?ssbauer isomer shifts have been calculated.
