Cryogenic buffer gas sources are ubiquitous for producing cold, collimated molecular beams quantum science, chemistry, and precision measurements. The molecules typically produced by laser ablating a metal target in the presence of donor gas, where radical interest emerges among reaction products due to barrier-free process or under thermal optical excitation. High-barrier reactions, such as between calcium hydrogen, should be precluded. Here, we study chemical reactions Ca three hydrogen...
Only bosonic molecular species have been directly laser cooled to date, primarily due an abundance of isotopes in nature and their simpler hyperfine structure. Fermionic molecules provide new opportunities for ultracold chemistry, quantum simulation, precision measurements. Here we report direct cooling a fermionic isotopologue, calcium monodeuteride (CaD). With nuclear spin <a:math...
Only bosonic molecular species have been directly laser cooled to date, primarily due an abundance of isotopes in nature and their simpler hyperfine structure. Fermionic molecules provide new opportunities for ultracold chemistry, quantum simulation, precision measurements. Here we report direct cooling a fermionic isotopologue, calcium monodeuteride (CaD). With nuclear spin I = 1, only 5 states need be addressed rotational closure optical cycling. These are unresolved typical experimental...
