Photoassociation rb
WebWe report continuous direct photoassociative formation of ultracold KRb molecules in the lowest vibrational levels (v′′=0−10) of the electronic ground state (X1Σ+), starting from 39K and 85Rb atoms in a magneto-optical trap. The process exploits a newfound resonant coupling between the 2(1),v′=165 and 4(1),v′=61 levels, which exhibit an almost equal … WebNov 7, 2024 · We investigate theoretically the formation of ultracold 39 K 87 Rb molecules on the lowest vibrational level of singlet ground electronic X 1 Σ + state via the Feshbach-optimized photoassociation. The probability density of colliding atomic pair at the short-range interatomic separation is significantly enhanced near Feshbach resonances.
