A Study of the Kinetic Parameters of Lu Laser Photoionization Scheme

摘要： Development of the laser photoionization method for obtaining 177Lu radionuclide for a medical purpose requires the knowledge of the light-saturation intensities at each stage of the Lu photoionization scheme (5d6s2 2D3/2?5d6s6p 4F5/2?5d6s7s 4D3/2?(53375 cm–1)), taking into account the used components of the hyperfine structure of transitions. The effective excitation cross sections of various hyperfine transition components for 175Lu, 176Lu, 177Lu, and 177mLu isotopes have been experimentally determined for radiations of pulsed tunable dye lasers pumped by copper-vapor lasers.
