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.

O17 Transforming sexual health systems through online services
Sexually Transmitted Infections, 2017IntroductionOnline sexual health services can transform sexual health systems through increased access and self-management. They are one element of the whole sexual health economy. Best practice facilitates appropriate movement of users between online and clinic services according to their sexual health need.MethodsUsing routinely collected, anonymised

An improved technique for the preparation of O17 targets
Nuclear Instruments and Methods, 1964Abstract This note describes an improved technique for producing thin films containing O 17 , suitable for nuclear spectroscopy. Tungsten oxide is obtained from the chemical reaction between a heated tungsten filament and enriched oxygen gas. The oxide is then evaporated on to thin carbon backings.

Covalent distribution of spin in V2O3:O17 nuclear resonance
Solid State Communications, 1974Abstract O 17 nuclear magnetic resonance has been observed in metallic V 2 O 3 with frequency shifts from (−0.10 ± 0.02)-(−0.05 ± 0.02) per cent between 170 and 460°K respectively, a linewidth of 37 ± 5 oe and spin-lattice relaxation rate 1/ T 1 ≈ 60 sec −1 at 296°K. From these quantities, covalency parameters f s /2 S = − 0.35 × 10 −3 and

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.

Thermonuclear reaction rate of O17(p,γ)F18
2005The O17(p,γ)F18 and O17(p,α)N14 reactions have a profound influence on hydrogen-burning nucleosynthesis in a number of stellar sites, including red giants, asymptotic giant branch (AGB) stars, massive stars, and classical novae. Previously evaluated thermonuclear rates for both reactions carry large uncertainties.

O17 Stereotyping of healthcare professionals’ personality traits in simulation training
Oral presentations, 2020Introduction Medical students and junior doctors’ perceptions about medical specialties are influenced by multiple factors. The hidden curriculum describes the implicit influences which shape the attitudes, behaviours and choices of medical graduates.1 Much of what is learnt through simulation occurs through powerful behavioural role modelling.

Improved health span and lifespan extension in a wide phylogenetic range of species is associated with upregulation of the environmental stress response (ESR). The ESR, driven by the transcription factor Nrf2, provides endogenous antioxidant defence to maintain intracellular redox balance.
