Анотація

Представлений новий релятивістський підхід до визначення зсуву і уширення лінії надтонкої структури важких атомів в атмосфері буферних газів, який базується на атомній калібру- вально-інваріантній релятивістській теорії збурень з оптимізованим нульовим наближенням Дірака-Фока з додатковим кореляційним потенціалом і обмінній теорії збурень для побудови міжатомного потенціалу. Як ілюстрація, наведені результати розрахунку зсуву і уширення надтонких ліній ряду важких атомів, зокрема, лужних і атома талію, в атмосфері буферних інертних газів. Показано, що акуратне урахування релятивістських, обмінно-кореляційних ефектів забезпечує адекватний опис енергетичних і спектральних властивостей важких атомів в атмосфері важких інертних газів.
