114. Efficient production routes of 129m,131m,133Xe for a novel medical imaging technique, gamma-MRI

Mateusz Chojnacki (Universite de Geneve (CH), CERN)

Applications

Oral

The future gamma-MRI imaging modality will allow the simultaneous exploitation the advantages of SPECT – sensitivity of gamma-ray detection, and MRI – spatial resolution and flexibility. The combination of these technique requires use gamma-emitting nuclei (like in SPECT) with higlhly polarized spins, leading to anisotropic emission of gamma-ray, and thus make possible to manipulate these...

110. Total Absorption Spectroscopy of isotopes with medical interest

Enrique Nacher (Instituto de Física Corpuscular (CSIC-UV))

Applications

Oral

Nuclear beta decay is often the first source of experimental information on nuclear structure when we are not too close to the drip lines. However, one of the main physical quantities relevant to this process, the beta-intensity distribution, is not easy to measure in medium-mass or heavy nuclei where high density of states is at reach within the Q-beta window. In these cases, the Total...

88. The study of the $\mathbf{^{21}Ne}$(p,$\gamma$)$\mathbf{^{22}Na}$ reaction at LUNA

Ragandeep Singh Sidhu (The University of Edinburgh)

Nuclear Reactions

Oral

The $\mathrm{^{21}Ne}$(p,$\gamma$)$\mathrm{^{22}Na}$ reaction is expected to be the main producer of the radioactive isotope $\mathrm{^{22}Na}$ ($t_{1/2}$ = 2.602 years) in novae. Novae explosions are the result of a thermonuclear runaway occurring on the surface of a white dwarf accreting material from a less evolved companion star in a close binary system that ejects a significant amount of...

65. Direct measurement of cross sections for the $^{114}$Cd(n,$\gamma$) reaction with En = 1 eV to 300 keV using DANCE

Prof. Benjamin Crider (Mississippi State University)

18/07/2023, 16:55

Nuclear Reactions

Oral

Cadmium has many practical applications where significant thermal neutron fluences are expected, owing to the large thermal capture cross-section of $^{113}$Cd. This feature has led to many applications that use cadmium to screen these thermal neutrons. Once such field where this is utilized is in non-destructive assay techniques that employ cadmium liners to interrogate spent fuel assemblies,...

66. Cross sections for 54Fe(n,n') 54Fe and 54Fe(n,p') 54Mn deduced from the detection of de-excitation  rays

Sally Hicks (University of Kentucky; University of Dallas)

18/07/2023, 17:10

Nuclear Reactions

Oral

Iron is an important component of many structural materials; examples include energy production complexes, laboratories, devices, and shipping containers that often cross borders. The properties of iron alloys in the structural materials—strength, ductility, and stability—depend on defects that develop and grow from neutron scattering and (n, p) and (n, ) reaction rates. 54Fe is only 5.5%...

49. Comprehensive Test of the Brink-Axel Hypothesis in the Energy Region of the Pygmy Dipole Resonance

Ms Maria Markova (University of Oslo)

18/07/2023, 17:25

Fundamental Symmetries and Interactions

Oral

The validity of the Brink-Axel hypothesis [1,2], which is especially important for numerous astrophysical calculations, is addressed for $^{116,120,124}$Sn below the neutron separation energy by means of three independent experimental methods. The $\gamma$-ray strength functions (GSFs) extracted from primary $\gamma$-decay spectra following charged-particle reactions with the Oslo method [3]...
