Description
The time scale ∆t parameter, which appears in the Bose-Einstein Correlations (BEC)
and treated in term of the Heisenberg uncertainty relations, is reexamined. Arguments
are given for the role of ∆t as a measure of the particles’ emission time rather than
representing the strength property of the correlated particles. In heavy ion collisions ∆t
measures the emission time duration of the particles produced from a nucleus of atomic
number A which is shown to be $\Delta t = \frac{m_{\pi}\alpha^2}{hc^2}A^{2/3}$
where a ≃1 fm that is, proportional to the nucleus surface area. This finding agrees rather
well with the experimental ∆t values deduced from the BEC analyzes of heavy ion collisions.
