The hyperfine shifts of 2S and 2P states of heliumlike atoms from helium to neon (both stable and unstable isotopes) have been calculated with accuracy better than 0.1 MHz. The fine structure and hyperfine structure parameters ( CS1,1,CS 1,0,CP1,1, CP1,0,D1, E1,1 and E1,0 ) are calculated using the double-basis-set wavefunctions in Hylleraas coordinates developed by Drake. Hyperfine shifts due to the electric quadrupole interaction, the Breit relativistic, QED and finite nuclear size effects have been included in the calculation. Our results are in good agreement with the recent experimental data.Dept. of Physics. Paper copy at Leddy Library: Theses & Major Papers - Basement, West Bldg. / Call Number: Thesis1998 .P36.
