摘要:

在非相对论量子力学框架下,研究了外加磁场和Aharanov-Bohm(AB)场作用下的改进屏蔽Kratzer势(ISKP).通过Nikiforov-Uvarov泛函分析(NUFA)方法求解薛定谔方程,得到了在外加磁场作用下ISKP的能谱和相应的波函数的封闭形式.所获得的能谱用于研究三个选定的双原子分子(H2,HCl和LiH)。据观察,目前的磁场和AB字段删除的简并为不同值的控制参数。在磁场和AB场的存在下,ISKP的热力学和磁性也进行了评估。讨论了控制势参数对所选双原子分子的热力学和磁学性质的影响。

英文摘要:

In the present study, the improved screened Kratzer potential (ISKP) is investigated in the presence of external magnetic and Aharanov-Bohm (AB) fields within the framework of non-relativistic quantum mechanics. The Schrodinger equation is solved via the Nikiforov-Uvarov Functional Analysis (NUFA) method and the energy spectra and the corresponding wave function for the ISKP in the presence of external magnetic fields are obtained in a closed form. The obtained energy spectra are used to study three selected diatomic molecules (H2, HCl and LiH). It is observed that the present of the magnetic and AB fields removes the degeneracy for different values of the control parameter. The thermodynamic and magnetic properties of the ISKP in the present of the magnetic and AB fields are also evaluated. The effects of the control potential parameter on the thermodynamic and magnetic properties of the selected diatomic molecules are discussed.
