摘要：

The metastable 5 D3/2 state of Ba+ is used to demonstrate the possibility of the ion storage technique for the measurement of extremely long lived states. The ions are confined in a r.f. quadrupole trap and excited by a strong pulsed tunable dye laser to the 6 P1/2 state which partially decays into the 5 D3/2 state. Sampling of the time development of the ground state population leads to the determination of the 5 D3/2 decay rate. Using He as a buffer gas at a pressure of about 10-6 mbar to initially store the ions, varying the gas density and extrapolating to zero pressure, we find for the lifetime {Mathematical expression}. © 1979 Springer-Verlag.
