Abstract

Radiative lifetimes of 17 excited states in Zr I, in the energy interval 29000 - 40974 cm^-1, have been investigated using the Time-Resolved Laser-Induced Fluorescence (TR-LIF) method. The levels belong to the 4d²5s5p, 4d³5p and 4d5s²5p electronic configurations were excited in a single - step process from levels belonging to the ground 4p²5s² a ³F or to low-lying 4p²5s² a ³P, a ⁵F terms. For 14 levels, the lifetimes have been measured for the first time. Experimental results are compared with theoretical calculations performed with a multiconfigurational relativistic Hartree-Fock method including core polarization effects.
