Abstract
The decays of ${}^{119m}\mathrm{Cs}$ and ${}^{119g}\mathrm{Cs}$ to ${}^{119}\mathrm{Xe}$ have been studied on mass-separated samples, using $\ensuremath{\gamma}$-ray and internal conversion electron measurements. Several new low-lying levels have been established in the ${}^{119}\mathrm{Xe}$ level scheme. Half-life evaluations for ${}^{119m}\mathrm{Cs}$ and ${}^{119g}\mathrm{Cs}$ have been revisited. The results are compared with other experimental data known in light odd-mass xenon isotopes and with calculations performed in the frame of the multishell interacting boson-fermion model.
