introduction:holmium-166 radionuclide is one of the most effective radionuclides used for targeted therapy with theranostic properties. one method to produce this radioisotope is via the decay of its parent (indirect method). in this study applicability of extraction chromatography (exc) for separation of no carrier added 166ho from neutron-irradiated natural dysprosium target followed by quali...

We show that in resonant inelastic x-ray scattering (RIXS) at the copper L and M edge direct spin-flip scattering is in principle allowed. We demonstrate how this possibility can be exploited to probe the dispersion of magnetic excitations, for instance magnons, of cuprates such as the high T(c) superconductors. We compute the relevant local and momentum dependent magnetic scattering amplitudes...

background: miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. the most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. in this research, we have surveyed and designed an am-be miniature neutron source fabrication. materials and methods: this investigation resulted in creation...

We compute the electric dipole moment d(n) of the neutron from a fully dynamical simulation of lattice QCD with 2+1 flavors of clover fermions and nonvanishing θ term. The latter is rotated into a pseudoscalar density in the fermionic action using the axial anomaly. To make the action real, the vacuum angle θ is taken to be purely imaginary. The physical value of dd(n) is obtained by analytic c...

This work reports the preparation of a Tc generator based on conversion of Mo produced by neutron irradiation, into insoluble magnesium Mo-molybdates compounds as matrix. The effect of magnesium salt types and concentration, Mg:Mo molar ratios, pH of molybdate solutions, eluate volume as well as the addition order of molybdate and magnesium solutions’ influences on the final Tc were evaluated. ...

The condensed matter nuclear reactions (CMNR) are thought to happen for trapped H(D) particles within some chemical (electro-magnetic) potential well with finite life time. As the life time is much longer than the collision time of two-body interaction of free particles, CMNR reaction rates are significantly (on the order of 19-20 in magnitude) enhanced if we compare with estimated reactions ra...

We have studied experimentally the angular distributions of fusion neutrons from plasmas of multi-keV ion temperature, created by 40 fs, multi-TW laser pulses in dense plumes of D2 and CD4 clusters. A slight anisotropy in the neutron emission is observed. We attribute this anisotropy to the fact that the differential cross section for DD fusion is anisotropic even at low collision energies, and...

Introduction BNCT is an effective method to destroy brain tumoral cells while sparing the healthy tissues. The recommended flux for epithermal neutrons is 10 n/cms, which has the most effectiveness on deep-seated tumors. In this paper, it is indicated that using D-T neutron source and optimizing of Beam Shaping Assembly (BSA) leads to treating brain tumors in a reasonable time where all IAEA re...

In the last four years, TheranostiCentre S.r.l., Berkion Technology LLC and ENEA have patented fabricated a first prototype of Compact Neutron Generator (CNG) currently under testing in laboratories. Besides usual applications field materials irradiation, this CNG - producing neutrons 2.45 MeV energy by using DD fusion reaction was conceived for neutron irradiation solid cancer’s tumour bed mea...
