Abstract

We have implemented a technique for precision mass comparison of two ions trapped simultaneously in a Penning trap in which each ion is alternately positioned at the center of the trap - where the cyclotron frequency is measured - and in a large cyclotron "parking" orbit. Systematic shifts in the cyclotron frequency ratio have been studied by comparing ¹³C₂H₂⁺/¹⁴N₂⁺ and ¹⁴N₂⁺/²⁸Si⁺. Using the method to compare ²⁸SiH₃⁺/³¹P⁺ we have obtained a new atomic mass for ³¹P, M[³¹P] = 30.973 761 999 7 (61) u.
