摘要: The states X1?+ and a3?+ correlated to the ground-state asymptote of Na (3s) Cs (6s) atoms have been experimentally investigated using high resolution Fourier-transform spectroscopy. hyperfine splitting state levels is partially resolved. Transitions asymptotic vibrational were recorded simultaneously. joint evaluation data both allows us determine accurate potential energy curves electronic states. Coupled-channels calculations are finally applied for deriving long range dispersion parameters exchange contribution molecular potentials, yielding a reliable description cold collisions between in their two different ground Scattering lengths Feshbach resonances predicted selected quantum
