Abstract
Separation of thallium isotopes (203Tl , 205Tl ) have been carried out by a 180º electromagnetic isotope separator. Thallium iodide as the charge material is used in a graphite crucible of calutron ion source. Under the pressure of 1 × 10-5 torr, thallium ions are extracted, accelerated and focused by the electrical lenses. The ions then traverse the main vacuum tank in circular paths, entering the magnetic field of 2547 Gauss and finally reach the collector. A number of chemical procedures have been employed for recovery and purification of the collected ions from the copper pockets. The final isotopic products have been characterized by a x-ray diffractometer, inductively coupled plasma-atomic emission spectrometer (ICP-AES) and a mass spectrometer. High pure thallium trioxide (Tl203 ) with 95.91% isotopic abundance for 203Tl has been confirmed.
