We considered the interaction of the localized surface plasmon in the lenticular metal particle with a point dipole source where it is defined the dependence of the rate of radiative and non-radiative relaxation on the distance from the particle. A modification of the particle geometry with an etching cone formation is proposed. It is shown that the presence of the cone changes the speed of non-radiative relaxation for the source located at a fixed distance from the surface. The results can be used to optimize the relative position of radiators and metal particle in experimental systems for the study of a wide class of phenomena associated with the interaction of the plasmon mode and a dipole source.
