Production and separation of no-carrier-added thallium isotopes from proton irradiated natHg2Cl2 matrix

► natHg2Cl2 target is used for production of Tl isotopes using natHg(p,xn) reaction. ► Trioctylamine is used for separation of Tl isotopes from bulk Hg2Cl2 target. ► Presence of bulk in the no-carrier-added product was verified with ICPOES. ► Hg contamination was less than 0.3 ppm in the final Tl fraction. ► Excitation function for natHg (p,xn) reaction was estimated by Alice 91 code.
