  Using a technique based on production of ion Coulomb crystals, the isotope
shifts of the 4s2 1S0 -> 4s5p 1P1 transition for all naturally occurring
isotopes of calcium as well as the hyperfine splitting of the 4s5p 1P1 state in
Ca-43 have been measured. The field shift and specific mass shift coefficients
as well as the hyperfine structure constants for Ca-43 have been derived from
the data.
