摘要: We report on spectroscopy of cold dysprosium atoms the $1001\,\mathrm{nm}$ transition and present measurements excited state lifetime which is at least $87.2(6.7)\,\mathrm{ms}$ long. Due to long we are able measure ratio polarizability ground $1064\,\mathrm{nm}$ be $0.828(0.129)$ by parametric heating in an optical dipole trap. In addition isotope shifts three most abundant bosonic isotopes with accuracy better than $30\,\mathrm{kHz}$.
