Abstract: 

The photorecombination spectrum of ⁴⁸Ti¹⁸⁺ was measured employing the merged electron-ion beams technique at a heavy-ion storage ring. The experimental electron-ion collision energy range 0-80 eV comprises all dielectronic recombination (DR) resonances associated with 2s → 2p (△N = 0) core excitations as well as trielectronic recombination (TR) resonances that involve 2s² → 2p² core double-excitations. At low collision energies DR resonances are observed that are associated with the excitation of metastable 2s 2p³P₀primary ions with nearly infinite lifetime for the isotope ⁴⁸Ti with zero nuclear spin. For the isotope ⁴⁷Ti with nonzero nuclear spin hyperfine quenching of these resonances occurs. The procedure for obtaining the associated time constant from a recombination measurement is outlined.
