  It is shown that $\alpha_s(E)$, the strong coupling constant, can be
determined in the non-perturbative regime from Bose-Einstein correlations
(BEC). The obtained $\alpha_s(E)$ is in agreement with the prescriptions dealt
with in the Analytic Perturbative Theory approach. It also extrapolates
smoothly to the standard perturbative $\alpha_s(E)$ at higher energies. Our
results indicate that BEC dimension can be considered as an alternative
approach to the short range measure between hadrons.
