Accurately measured wavelengths of ZnI and ZnII lines of astrophysical interest

Zinc is an element of importance in many research fields within astronomy a nd astrophysics, from cosmology to stellar atmosphere dynamics. With the ai m of improving three decades old measurements of zinc lines of astrophysica l interest, emission spectra of Zn I and Zn II have been recorded using a F ourierTransform Spectrometer with a hollow cathode light source. Revised en ergies for previously known levels are derived from the measurements for Zn I 3d(10)4snl and for Zn II 3d(10)nl and 3d(9)4s(2). Isotope shifts are obs erved in Zn II lines involving the 3d(9)4s(2) configuration. The accuracy o f prominent lines and energy levels are about 0.001-0.003 cm(-1) and 0.002- 0.005 cm(-1) respectively.
