Investigation of activation cross-sections of proton induced nuclear reactions on natTl up to 42 MeV: review, new data and evaluation

TL;DR

This paper reviews and provides new experimental data on proton-induced nuclear reaction cross-sections on natural thallium up to 42 MeV, aiding the production of medical isotope 201Tl and comparing results with existing data and models.

Contribution

It offers new experimental cross-section data for multiple isotopes and evaluates these against literature, IAEA data, and nuclear reaction models.

Findings

New cross-section measurements up to 42 MeV for various isotopes.

Comparison shows agreement and discrepancies with literature and models.

Provides evaluated data useful for medical isotope production.

Abstract

Cross-sections of proton induced nuclear reactions on natural thallium have been studied for investigation of the production of the medical important 201Tl diagnostic radioisotope. The excitation functions of 204mPb, 203Pb, 202mPb, 201Pb, 200Pb, 199Pb, 202Tl (direct, cumulative), 201Tl (direct, cumulative), 200Tl(direct), and 203Hg were measured up to 42 MeV proton energy by stacked foil technique and activation method. The experimental data were compared with the critically analyzed experimental data in the literature, with the IAEA recommended data and with the results of model calculations by using the ALICE-IPPE, EMPIRE-II and TALYS codes.
