(a) PA spectrum of the v = 10 vibrational level of Cs2 long-range 0g− state without the magnetic field. (b) The number of atoms as a function of the frequency detuning of the PA laser with the magnetic fields of 87 G (red dots), 96 G (violet dots), 108 G (green dots), and 120 G (navy dots) for J = 2. The solid curves are the fittings using a Lorentzian function.
