Abstract

The dipole and quadruple Oscillator strengths for Hydrogen atom are computed under the effect of More General Exponential Cosine Screened Coulomb (MGECSC) potential which describes Debye as well as quantum plasma as its special cases. The wavefunctions are computed through numerical simulation using the accurate Numerov method. The variation of the oscillator strengths for different transitions in plasma embedded Hydrogen with respect to different parameters of the modelling potential are investigated. As per the present calculations, the dipole oscillator strengths for Debye plasma, decrease as the parameter \(\upmu \) increases. In contrast, for quantum plasma, the dipole oscillator strength values increase as the parameters \(\upmu \), b, and c of the potential increase. For quadruple oscillator strengths, few deviations are observed due to combined effect of three parameters of potential.

用MGECSC势模拟稠密等离子体下氢原子的偶极子和四重振子强度

在描述德拜势和量子等离子体的更一般指数余弦屏蔽库仑势的作用下，计算了氢原子的偶极子和四重振子强度。采用精确的数值模拟方法计算了波函数。研究了嵌入氢的等离子体中不同跃迁的振子强度随模拟电位参数的变化。根据目前的计算，德拜等离子体的偶极子振子强度随着参数\(\upmu \)的增大而减小。相反，对于量子等离子体，偶极子振子强度值随着势的参数\(\upmu \)、b和c的增加而增加。对于四振子强度，由于三个电位参数的共同作用，观测到的偏差很小。

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
