Theoretical analysis of the polarizability agrees well with experimental findings. Although the polarizability can vary by more than 30%, a \"magic\" angle between the laser polarization and the quantization axis is found where the polarizability of the $|N=0,m_N=0>$ and the $|N=1,m_N=0>$ states match. At this angle, rotational decoherence due to the mismatch in trapping potentials is eliminated, and we observe a sharp increase in the ","authors_text":"A. Chotia, A. Petrov, B. Neyenhuis, B. Yan, D.
