Detection of nonlinear resonances for trapped Pr⁺ ions — •Adam Buczek, Gustaw Szawiola, Adrian Walaszyk, Wojciech Koczorowski, Danuta Stefanska, and Ewa Stachowska — Chair of Atomic Physics, Poznan University of Technology, Nieszawska 13, PL-60-965 Poznan, Poland

A Paul trap allows selection of trapped ions according to ionization stage and mass. Following [1,2,3], the deviation of the trap potential from ideal quadruple form leads to nonlinear resonances. The observation of this effects are presented for Pr⁺ ions confined in a Paul trap with a ring electrode diameter of 2 cm.

The presented work has been supported by the project of Poznan University of Technology BW 63-028/06.
