摘要：

We report a search for a scheme of selective laser stepwise ionisation of radionuclide Ni-63 by radiation of a dye laser pumped by a copper vapour laser. A three-stage scheme is found with ionisation through an autoionising state (AIS): 3d(8)4s(23)F(4)(E = 0) -> 3d(9)4p(1)F(3)(o)(31030.99 cm(-1)) -> 3d(9)4d(2)[7/2](4)(49322.56 cm(- 1)) -> AIS(67707.61 cm(-1)) which, by employing saturated radiation intensities provides the ionisation selectivity of above 1200 for Ni-63.
