Abstract: By making the effective potential approximation, the Schrödinger equation for confined particles in a quadrupole ion trap was solved and its energy eigenvalues were evaluated. The partition function and then entropy for the ensemble trapped particles in equilibrium were obtained and analyzed. This research can be helpful for investigating the properties of trapped particles and also for designing and construction of quadrupole ion traps.
