The relevant Schrödinger wave equation is solved using a hybrid approach that combines the tridiagonal matrix method and the asymptotic iteration method. Through this solution, the system’s energy levels, probability densities, dipole polarizabilities, and oscillator strengths are calculated. The changes in plasma density, plasma shielding effect, and endofullerene parameters significantly influence the dynamics of these fundamental properties. Specifically, the analysis of oscillator strengths reveals the strength of electromagnetic interactions during transitions within the system and details how these transitions are affected by plasma, endofullerene confinement, spherical confinement, and angular interactions. Changes in dipole polarizability illustrate how the atom evolves under the influence of these external factors, while differences in oscillator strengths play a critical role in understanding the efficiency of electronic transitions and the system’s interaction with electromagnetic waves. This work contributes to a better understanding of endohedral molecular systems in quantum plasma environments and provides a valuable foundation for modeling the properties of such systems. Moreover, as it serves as an important reference for broader investigations into the dynamics of noncentral endohedral fullerene and quantum plasma interactions at the atomic and molecular levels, it sheds light on future experimental and theoretical studies.</div>","PeriodicalId":556,"journal":{"name":"Few-Body Systems","volume":"66 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00601-025-01993-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144090942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
