A symmetric expression is derived for the coulombic interaction betwee
n two species of thermal ions trapped in a r.f. trap. Consequently, th
e oscillation frequencies of the weak and the strong oscillation modes
of the system and their relevant conditions are expressed quantitativ
ely. When two kinds of oppositely charged ions are trapped, a strong c
oupling region near a strong correlation line always exists, so that t
he coupling type can be controlled by selecting a suitable operation p
oint. The detectability and the evolution of the electrical signals by
r.f. resonance absorption detection are also discussed.
