title: [Polymer chain with eliminated volume in an exterior field].
abstract: The problem of the behaviour of a polymer chain with excluded volume in an external attractive potential field was considered. It was found that the phase transition (the capture of a polymer by a potential pit), is the phase transition of the second kind; the excluded volume affects neither the temperature, nor the kind of phase transition, but it influences essentially the structure of the system after capture. An analysis of this structure was undertaken; the dependence of the critical temperature on the parameters of the pit was calculated.
