Properties of Lithium-7

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.
