摘要：

We calculate, within the pseudopotential approximation, a one-dimensional scattering amplitude and effective one-dimensional interaction potential for atoms confined transversally by an atom waveguide or highly elongated "cigar"-shaped atomic trap. We show that, in the low-energy scattering regime, the scattering process degenerates to a total reflection, suggesting an experimental realization of a famous model in theoretical physics-a one-dimensional gas of impenetrable bosons ("Tonks" gas). We give an estimate fur suitable Experimental parameters for alkali atoms confined in waveguides.
