Ultracold D + H2 (v = 4, j = 0) reaction dynamics: Long-range interactions, diagonal Born-Oppenheimer correction, and a diabatic geometric phase treatment.

Ultracold hydrogen-exchange reactions have long provided a key platform for identifying subtle quantum mechanical effects in triatomic systems. The long-range interactions, diagonal Born-Oppenheimer correction (DBOC), and geometric phase (GP) have be…
