Calculation of the hyperfine structure of Dy, Ho, Cf, and Es
Calculation of the hyperfine structure of Dy, Ho, Cf, and Es
A recently developed version of the configuration interaction (CI) method for open shells with a large number of valence electrons has been used to study two heavy atoms, californium (Cf, $Z=98$) and einsteinium (Es, $Z=99$). Motivated by experimental work to measure the hyperfine structure (HFS) for these atoms, we perform …
