  The interaction between kink and radiation in nonlinear one-dimensional real
scalar field is investigated. The process of discrete vibrational mode
excitation in $\phi^4$ model is considered. The role of this oscillations in
creation of kink and antikink is discussed. Numerical results are presented as
well as some attempts of analytical explanations. An intriguing fractal
structure in parameter space dividing regions with creation and without is also
presented.
