Abstract
The problem of determining the solitons generated from symmetric real initial conditions in the Nonlinear Schrödinger equation is revisited. The corresponding Zakharov- Shabat scattering problem is solved for an example of a real double-humped rectangular initial pulse form. It is found that this real symmetric pulse generates moving soliton pulse pairs corresponding to eigenvalues with non-zero real parts.
