The ${}^{14}\mathrm{N}(p,\ensuremath{\gamma}{)}^{15}\mathrm{O}$ reaction, which controls energy production in the CNO cycle, has contributions from both resonance and direct captures to ground excited states. overall normalization of is defined by corresponding asymptotic coefficients (ANCs). Especially important ANC for subthreshold state ${}^{15}\mathrm{O}$ at $\ensuremath{-}0.504\mathrm{keV}$ since capture through this dominates reaction rate stellar energies. In order determine ANCs...
The ${}^{15}\mathrm{N}(p,\ensuremath{\gamma}){}^{16}\mathrm{O}$ reaction provides a path from the CN cycle to CNO bi-cycle and tri-cycle. measured astrophysical factor for this is dominated by resonant capture through two strong ${J}^{\ensuremath{\pi}}={1}^{\ensuremath{-}}$ resonances at ${E}_{R}=312$ 962 keV direct ground state. Asymptotic normalization coefficients (ANCs) seven excited states in $^{16}\mathrm{O}$ were extracted comparison of experimental differential cross sections...
The activation cross sections of $(d,p)$, $(d,2p)$, and $(d,p\ensuremath{\alpha})$ reactions on $^{27}\mathrm{Al}$ were measured in the energy range from 4 to 20 MeV using stacked-foils technique. Following a previous extended analysis elastic scattering, breakup, direct reaction deuterons $^{27}\mathrm{Al}$, for energies 3 60 MeV, preequilibrium statistical emissions are considered same range. Finally, all deuteron-induced including present data up deuteron properly described due...
The activation cross sections of $(d,p)$, $(d,2n)$, $(d,3n)$, and $(d,2p)$ reactions on $^{63,65}\mathrm{Cu}$ were measured in the energy range from 4 to 20 MeV using stacked-foil technique. Then, following available elastic-scattering data analysis that provided optical potential for reaction cross-section calculations, an increased effort was devoted breakup mechanism, direct stripping, pre-equilibrium compound-nucleus corrected stripping decrease total section. overall agreement between...
Several experiments around the world are looking for a new particle, named Dark Boson, which may do link between Ordinary Matter (which forms basically stars, planets, interstellar gas...) and Hidden Sectors of Universe. This if it exists, would act as messenger fundamental interaction nature. In this paper, underlying theory will be introduced first. A non-exhaustive summary experimental studies carried out to date foreseen in incoming years presented after,including 8 Be anomaly. The last...
Background: The high complexity of the deuteron-nucleus interaction from deuteron weak binding energy 2.224 MeV is also related to a variety reactions induced by deuteron-breakup (BU) nucleons. Thus, specific noncompound processes as BU and direct (DR) make deuteron-induced so different with other incident particles. scarce consideration only pre-equilibrium emission (PE) compound-nucleus (CN) mechanisms led significant discrepancies experimental results that recommended reaction cross...
The activation cross sections for production of $^{51}\mathrm{Cr}$, $^{52,54,56}\mathrm{Mn}$, $^{59}\mathrm{Fe}$, and $^{55,56,57,58}\mathrm{Co}$ radioisotopes in deuteron-induced reactions on natural Fe were measured at deuteron energies up to 20 MeV. Then, within an extended analysis interactions with ${}^{\mathrm{nat}}$Fe, all processes from elastic scattering until the evaporation fully equilibrated compound system have been taken into account. Following available elastic-scattering data...

Particular attention paid description breakup mechanism direct stripping...
For validating activation cross-section data in the energy range relevant to IFMIF (International Fusion Material Irradiation Facility), fast neutron sources were developed utilizing NPI variable-energy cyclotron U-120M.Novel concept of source reaction was investigated for a generation white -(IFMIF-like) -spectrum on cyclotron.The deuteron break-up process induced by 37 MeV protons flowing heavy water target found produce neutrons with high intensity, mean 14 and spectrum extending 32...
The $^{20}\mathrm{Ne}$$(p,\ensuremath{\gamma})$$^{21}\mathrm{Na}$ reaction rate at stellar energies is dominated by capture to the ground state through tail of a subthreshold resonance an excitation energy 2425 keV in $^{21}\mathrm{Na}$. Both resonant and direct contribute while captures other bound states are negligible. overall normalization determined asymptotic coefficient (ANC). Simultaneously this ANC determines proton partial width state. To determine ANC,...

Background: Specific noncompound processes such as breakup (BU) and distinct direct reactions (DR) make deuteron-induced different from with other incident particles. Significant discrepancies measured cross sections were caused by taking into account only the pre-equilibrium emission (PE) compound-nucleus (CN) mechanisms while microscopic calculation of inclusive BU DR is still investigated numerically. Thus, reaction recommended most recently for high-priority elements are based on data...
