Excitation Functions for the Formation of ^200,201,202Pb by Proton Induced Nuclear Reactions on Enriched ²⁰⁴Pb

Abstract

Proton induced reactions on enriched 204 Pb / Excitation functions / Stacked foil technique/ 200,20,,202p b / Integm l y ie l ds Abstract Excitation functions for the formation of 200,20, ' 202 Pb in the interactions of 47.9% isotopically enriched 204 Pb with protons have been measured by the stacked foil technique within the proton energy range of 25.7-39.7 MeV. The maximum cross section for the 20, Pb formation (mother nucleus of medically important 201 T1) was found to be (700±100) mb at a flat maximum ranging from 33 to 37 MeV. The cross section results are compared with calculations based on the hybrid model of nuclear reactions using the computer code Overlaid Alice.

“…Szelecsenyi et al [201] compiled and evaluated the cross sections and the thick target yield data for proton induced reactions on TI. A need was identified [201] to extend and complete the cross section measurements of 203 Tl(p,p2n) 201 Tl, 203 Tl(p,pn) 202 Tl and 205 Tl(p,3n) 203ml m2m3 Pb processes. Zaitseva et al [202] reported the excitation functions for formation of **>*>< *>2pb with 25.7 to 39.7 MeV protons on 47.9% isotopically enriched 204 Pb.…”
