By inducing a Raman transition using a pair of Gaussian and Laguerre-Gaussian laser beams, we realize a $^{87}\mathrm{Rb}$ condensate whose orbital angular momentum (OAM) and its internal spin states are coupled. By varying the detuning and the coupling strength of the Raman transition, we experimen...
