Activation cross-section measurement of proton induced reactions on cerium

Abstract

In the framework of a systematic study of proton induced nuclear reactions on lanthanides we have measured the excitation functions on natural cerium for the production of 142,139,138m,137 Pr, 141,139,137m,137g,135 Ce and 133 La up to 65 MeV proton energy using the activation method with stacked-foil irradiation technique and high-resolution -ray spectrometry. The cross-sections of the investigated reactions were compared with the data retrieved from the TENDL-2014 and TENDL-2015 libraries, based on the latest version of the TALYS code system. No earlier experimental data were found in the literature.The measured cross-section data are important for further improvement of nuclear reaction models and for practical applications in nuclear medicine, other labeling and activation studies.

Improving the Effect of Cancer Cells Irradiation with X-rays and High-Energy Protons Using Bimetallic Palladium-Platinum Nanoparticles with Various Nanostructures

“…Although the radiation doses used for X-rays and protons were the same, they differed in energy. The high-energy protons (225 MeV) used in our experiment are characterized by a relatively small cross-section, which is the probability of a nuclear reaction–in this case, the reaction between protons and the high-Z metal PdPt NPs [ 37 ]. At lower radiation energies, the chance for such a reaction is much higher, and hence the physical mechanism of radiosensitization (by generating, e.g., gamma radiation or secondary electrons) could be more involved [ 38 ].…”

Activation cross sections of proton induced nuclear reactions on neodymium up to 65 MeV

“…We already investigated the production routes of these radionuclides by using deuteron induced reactions on neodymium [10]. We also have investigated possible production routes of these radionuclides via proton and deuteron induced reactions on La [11], Ce [12,13] and Pr [14,15].…”
