| Abstract |
A six-dimensional potential energy surface is constructed for the spin-polarized triplet state of CaF-CaF by \textitab initio calculations at the CCSD(T) level of theory, followed by Gaussian process interpolation. The potential is utilized to calculate the density of states for this bi alkaline-earth-halogen system where we find the value 0.038 μK−1, implying a mean resonance spacing of 26 μK in the collision complex. This value implies an associated Rice-Ramsperger-Kassel-Marcus lifetime of 18 μs, thus predicting long-lived complexes in collisions at ultracold temperatures. |

The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
