This is a stand-alone version of chapter 2 of Mathis Fischer’s PhD thesis [1]. It aims to provide an overview of the physical properties of the bosonic Lithium isotope 7Li, that are useful and relevant for quantum gas experiments. While there are great resources on the relevant physical properties of Rubidium, Cesium, Sodium, Potassium, and the fermionic isotope 6Li by Daniel Steck, Tobias Tiecke, and Michael Gehm [2–7], there is - to the best of our knowledge - no comparable manuscript discussing the properties of 7Li. A review article by Randall G. Hulet, Jason H. V. Nguyen, and Ruwan Senaratne [8] discusses methods for the preparation of cold gases of both Lithium isotopes. Here we summarize these results together with other resources to provide the relevant data solely for 7Li in a similar format as from Michael Gehm for 6Li. We focus on the important properties that need to be considered for successful Bose-Einstein condensation of 7Li.
