We consider the Henon equation where Ω is the unit ball in R~N, a > 0 is aj constant, and p is superlinear and subcritical, that is When the dimension N > 3, it is known that the least-energy solutions cannot be, as p approaches the critical exponent, radially symmetric, and the maximum point will converge to the boundary.

This new form factor satisfies the crossing symmetry law of strongly interacting particle scattering amplitudes transfered from t-channel to s-channel or the inverse.
