  "abstract": "We report on resonance ionization laser spectroscopy measurements performed on both neutron-deficient and neutron-rich thulium ($\\mathrm{Tm}, Z=69$) isotopes. Isotope shifts were determined for three atomic ground-state transitions at wavelengths of $389.8\\,\\mathrm{nm}$, $388.4\\,\\mathrm{nm}$, and $388.8\\,\\mathrm{nm}$ in the isotopes ${}^{152\\mathrm{m}}\\mathrm{Tm}$, ${}^{153}\\mathrm{Tm}$, ${}^{154\\mathrm{m}}\\mathrm{Tm}$, and ${}^{169}\\mathrm{Tm}$. In addition, for the $389.8\\,\\mathrm{nm}$ transition, measurements were extended to the isotope ${}^{170}\\mathrm{Tm}$, and the hyperfine structure was partially resolved for all five isotopes. For this transition, the isotope shift could be determined for one more isotope, ${}^{154\\mathrm{m}}\\mathrm{Tm}$. From the extracted hyperfine coupling constants, the nuclear magnetic dipole moment for ${}^{152\\mathrm{m}}\\mathrm{Tm}$ was determined for the first time, resulting in $μ\\left({}^{152\\mathrm{m}}\\mathrm{Tm}\\right) = 5.8(3) μ_\\mathrm{N}$. Furthermore, the mean-square nuclear charge radius $δ\\langle r^2\\rangle^{152\\mathrm{m},169} = -1.87(17)\\,\\mathrm{fm}^2$ for ${}^{152\\mathrm{m}}\\mathrm{Tm}$ was extracted from the measured isotope shifts.",
