New developments in the experimental data for charged particle production of medical radioisotopes
The goal of the present work is to give a review of developments achieved
experimentally in the field of nuclear data for medically important
radioisotopes in the last three years. The availability and precision of
production related nuclear data is continuously improved mainly experimentally.
This review emphasizes a couple of larger fields: the Mo/Tc generator problem
and the generator isotopes in general, heavy alpha-emitters and the rare-earth
elements. Other results in the field of medical radioisotope production are
also listed.Comment: in Journal of Radioanalytical and Nuclear Chemistry 201
Activation cross-sections of proton induced reactions on Sm up to 65 MeV
Activation cross sections for proton induced reactions on Sm are presented
for the first time for
Sm(p,xn)Eu,
Sm(p,x)Sm,
Sm(p,x)Pm and
Sm(p,x)Nd up to 65 MeV. The cross sections were measured via
activation method by using a stacked-foil irradiation technique and high
resolution gamma ray spectroscopy. The results were compared with results of
the nuclear reaction codes ALICE, EMPIRE and TALYS (results taken from TENDL
libraries). Integral yields of the activation products were calculated from the
excitation functions.Comment: arXiv admin note: text overlap with arXiv:1411.716
Cross sections of deuteron induced reactions on Sm for production of the therapeutic radionuclide Sm and Sm
At present, targeted radiotherapy (TR) is acknowledged to have great
potential in oncology. A large list of interesting radionuclides is identified,
including several radioisotopes of lanthanides, amongst them Sm and
Sm. In this work the possibility of their production at a cyclotron was
investigated using a deuteron beam and a samarium target. The excitation
functions of the Sm(d,x)Sm reactions were determined for
deuteron energies up to 50 MeV using the stacked-foil technique and
high-resolution -ray spectrometry. The measured cross sections and the
contributing reactions were analyzed by comparison with results of the ALICE,
EMPIRE and TALYS nuclear reaction codes. A short overview and comparison of
possible production routes is given
