Abstract
We developed a nonperturbative technique in field theory to obtain the ground state properties of He-4 nucleus. Here, the sigma-meson effect s are simulated through isosinglet scalar cloud of pairs of off-shell pions with a coherent state. The analysis de facto replaces the scalar isoscalar potential in nuclear physics by multipion condensates. Also , we discuss the two hard photons production from the off-shell pi(+)p i(-) pair as present through pion cloud within the framework of the mo del.
