“…Thick target yields data were reported by Bondarenko and Rudenko [8] using 3 MeV deuterons for activation analysis; Vakilova et al [9] also investigated the production yield for the determination of trace elements by deuteron activation. Dmitriev et al [10] made a systematic study of thick target yields at 22 MeV deuterons induced reactions on a large number of target elements.…”

In the frame of a systematic study of activation cross sections of deuteron induced reactions, experimental cross section data were measured on Mn (monoisotopic 55 Mn) up to 50 MeV for the formation of 56,54,52 Mn, 48 V and 51 Cr by using stacked-foil activation method and high resolution gamma spectrometry. The experimental data are compared with the earlier published data and with the results predicted by the ALICE-IPPE-D and EMPIRE-II-D theoretical codes, and with the data taken from the on-line TENDL-2017 library.

“…In the literature only a few works containing data on deuteron induced activation cross sections on selenium were found. Some of the earlier measurements were done on enriched monoisotopic targets (Miskel [1], Debuyst [2], Paans [3], Qaim [4], Dmitriev [5] and Vakilova [6] are limited to low energy and all are related to study of medical radioisotope production and nuclear reaction mechanisms or nuclear structure studies.…”

In the frame of a systematic study of deuteron induced nuclear reactions on all elements, activation cross sections on $$^{\mathrm {nat}}$$ nat Se were investigated. Excitation functions were measured up to 50 MeV particle energy for production of $$^{\mathrm {82}}$$ 82 Br(m$$+)$$ + ) ,$$^{\mathrm {80m}}$$ 80 m Br, $$^{\mathrm {77}}$$ 77 Br(m$$+)$$ + ) ,$$^{\mathrm {76}}$$ 76 Br(m$$+)$$ + ) , $$^{\mathrm {75}}$$ 75 Br, $$^{\mathrm {75}}$$ 75 Se(cum), $$^{\mathrm {73}}$$ 73 Se(cum), $$^{\mathrm {76}}$$ 76 As,$$^{\mathrm {74}}$$ 74 As, $$^{\mathrm {73}}$$ 73 As(cum), $$^{\mathrm {72}}$$ 72 As and $$^{\mathrm {71}}$$ 71 As(cum) by using the activation method through stacked foil irradiation followed by off-line gamma-ray spectrometry.

The yield of a radionuclide is an important physical quantity, determining the number of radioactive atoms in the irradiated samples. For low and intermediate energy protons and deuterons, 7 Be forms from lithium and boron in the nuclear reactions 7 Li (p, n), 10 B (p, α), 11 B (p, αn), 6 Li (d, n), 7 Li (d, 2n), 10 B (d, αn), 11 B (d, α2n). For purposes of using a cyclotron in activation analysis, the 7 Be yield obtained by irradiating targets with charged particles accelerated in the U-150 cyclotron at the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan was investigated [1][2][3][4][5]. The yield of 7 Be in the reactions Li(d, n) and Be(d, n) was also measured at deuteron energies 25 and 40 MeV [5].Another method for obtaining 7 Be consists in using recoil protons and deuterons which form in a nuclear reactor as a result of (n, p) or (n, d) and elastic or inelastic scattering of fast neutrons interacting with hydrogen nuclei [6].The present article presents experimental results from a study of 7 Be production by irradiating natural lithium and boron by recoil protons and deuterons in a nuclear reactor.The radionuclide yield is given by the expression where A is the activity of the radionuclide at t cool = 0, λ is the decay constant, m is the mass of lithium or boron in the irradiated sample, and t irr is the duration of irradiation. The specific activity of 7 Be referred to unit mass of a chemical element in the irradiated sample was estimated from the relation A = N γ exp (-λt cool /(mt meas ωI γ ),where N γ is the number of measured counts, t meas is the duration of a measurement, η is a geometric detection factor, ω is the attention efficiency, I γ is the intensity of the gamma radiation, and t cool is the cooling time. 7 Be possesses a half-life which is suitable for measurements T 1/2 = 53.61 days and emitted gamma ray energy E γ =
