  The correlation of $\alpha\alpha$ was probed via measuring the transverse
momentum $p_{T}$ and width $\delta p_{T}$ of one $\alpha$, for the first time,
which represents the spatial and dynamical essentialities of the initial
coupling state in $^{8}$Be nucleus. The weighted interaction vertex of
3$\alpha$ reflected by the magnitudes of their relative momentums and relative
emission angles proves the isosceles triangle configuration for 3$\alpha$ at
the high excited energy analogous Hoyle states.
