Collisions in a quantum gas of bosonic 23Na39K molecules — •Mara Meyer zum Alten Borgloh1, Philipp Gersema1, Leon Karpa1, Kai Konrad Voges1, Jule Caroline Heier1, Silke Ospelkaus-Schwarzer1, Charbel Karam2, and Olivier Dulieu2 — 1Institut für Quantenoptik, Leibniz Universität Hannover — 2Université Paris-Saclay, CNRS, Laboratoire Aimé Cotton
We report about our experiments with quantum gases of polar 23Na39K molecules. We discuss both atom-molecule and molecule-molecule collisions including the origin of loss processes in a cloud of chemically stable 23Na39K molecules.
Furthermore, we discuss a method for suppressing molecular loss using two optical photons at Raman resonance, leading to a potential barrier that protects the colliding molecules from reaching the short range.
