Tán Xạ Compton Cộng Hưởng Của Photon Bởi Các Nguyên Tử Helium Trong Plasma Thiên Văn Lorentzian
Tóm tắt
Chúng tôi nghiên cứu các ảnh hưởng của plasma thiên văn Lorentzian đối với hiện tượng tán xạ Compton cộng hưởng của photon bởi các trạng thái cơ sở và trạng thái kích thích của helium. Các năng lượng của trạng thái bị ràng buộc-nâng cao trong môi trường plasma được xác định bằng cách sử dụng các hàm sóng mũ tương quan cao trong khuôn khổ phương pháp biến thiên Ritz. Các tiết diện tán xạ Compton cộng hưởng trong plasma Lorentzian giữa trạng thái $$\hbox {1s}^{2}{\,}^{1}\hbox {S}$$ và 1s2p $$^{1}\hbox {P}$$, 1s2s $$^{1}\hbox {S}$$ và 1s3p $$^{1}\hbox {P}$$, 1s3s $$^{1}\hbox {S}$$ và 1s3d $$^{1}\hbox {D}$$ được báo cáo dưới dạng hàm của chỉ số quang phổ và tham số plasma. Tính chất phi nhiệt của các plasma Lorentzian cho thấy những đặc điểm thú vị về các tiết diện tán xạ Compton cộng hưởng.
