Scientific paper

We study the numerical solution to the full field equations describing the evolution of a spherically symmetric global texture. We concentrate on the evolution of the fields after the texture collapses. We compare this result with a previous analytical solution found by Turok and Spergel using the nonlinear σ model approximation. The energy produced in massive modes is of the order of 1016 GeV and is almost independent of the initial size of the texture.
