The 3.06 and 3.85 MeV states in O17
Nuclear Physics, 1964Abstract The 3.06 and 3.85 MeV states in O17 have been excited by the reaction C14(α, n)O17, the gamma-ray de-excitation of these states being observed in coincidence with neutrons. The attenuated Doppler shifts of the gamma rays were measured and lead to lifetime estimates of 1.2−0.6+0.8 and ≦ 0.25 × 10−13 sec respectively.

Microwave dielectric properties of La5(Ti4B)O17 and Nd5(Ti4B)O17 (B = Cr, Fe) ceramics
Journal of Materials Science: Materials in Electronics, 2014Compositions in the A5B5O17 (A = La, Nd, B = Cr, Fe) series were processed through a mixed oxide solid state sintering route. X-ray diffraction revealed an orthorhombic (Pnnm) symmetry for La5Ti4FeO17 and monoclinic (P21/b) symmetry for Nd5Ti4FeO17, associated with the higher tolerance factor of Nd5Ti4FeO17 than Nd5Ti4CrO17.

EPR Study of O17- on Magnesium Oxide
The Journal of Chemical Physics, 1971The EPR spectrum of O17- on MgO has been obtained by the reaction of N2O containing 71.9% oxygen-17 isotope with trapped electrons on an MgO surface. The spectrum of the ion is characterized by g ⊥=2.042 and g ∥=2.0013 with A⊥=19.5±0.1G and A ∥=103.2±0.1G. A quadrupole interaction of Q⊥=1.3±0.2G was also determined.

O17 Douleurs neuropathiques et SEP
Douleurs : Evaluation - Diagnostic - Traitement, 2007La sclerose en plaques (SEP) s’accompagne frequemment de douleurs. Certaines sont liees directement au processus lesionnel et de mecanisme neuropathique central, d’autres sont les consequences indirectes de la maladie. Ces douleurs aggravent le handicap de ces patients en particulier sur le plan professionnel et alterent la qualite de vie des patients.

Nonresonant p -wave direct capture and interference effect observed in the O16(n,γ)O17 reaction
, 2020We measured the total capture cross section of the $^{16}\mathrm{O}(n,\ensuremath{\gamma})^{17}\mathrm{O}$ reaction, as well as partial cross sections leading to the ground (${J}^{\ensuremath{\pi}}=5/{2}^{+})$ and first-excited (${J}^{\ensuremath{\pi}}=1/

Preparation of O17-labelled glasses and glass precursers
Materials Research Bulletin, 1980Abstract Novel methods for the preparation of O-17 labelled ionic oxide glasses which are label conservative and yield glasses at the same enrichment level as the starting materials, were designed to provide materials for the investigation of the O-17 NMR and the vibrational spectra.

A new phosphor of the type Gd8(1-x) Eu8 x V2 O17 (x=0-1.0) was synthesized through the solid-state reaction ceramics method. A pure phase formation was verified by using X-ray powder diffraction measurements.

Quadrupole matrix elements in O17 and F17
Nuclear Physics, 1964Abstract The model of the low-lying states of O17 and F17 in which a distortion of the O16 core is produced by a two-particle central interaction between the odd nucleon and the core nucleons is investigated in first order perturbation theory. It is found that T = 1 excitations of the core give appreciable contributions to E2 matrix elements.
