The Ep = 2.66 MeV resonance in O16(p, p)O16
Nuclear Physics, 1965Abstract The absolute differential cross section has been measured over the Ep = 2.66 MeV resonance [Ex(F17) = 3.10 MeV] in O16(p, p)O16 at the following angles in the centre-of-mass system: 54.5°, 70.5°, 90.0°, 107.0°, 125.5°, 140.5° and 151.3°. Also angular distributions (15 angles from θc.m.

Structure of the O16 polysaccharide from Escherichia coli O16:K1: An NMR investigation
Carbohydrate Research, 1994The polysaccharide moiety of the O16 antigen (lipopolysaccharide) consists of D-glucopyranose, D-galactofuranose, L-rhamnopyranose, and 2-acetamido-2-deoxy-D-glucopyranose in the molar ratios 1:1:1:1. It is O-acetylated with one acetyl group per repeating unit.

Gaseous nitrogen, enriched to 95% in N/sup 15/, was enclosed in a small duralumin chamber into which a beam of protons, collimated to a 16-in. diameter, could be directed through entrance and exit foils of thin nickel. Center-of mass differential scattering cross sections were measured at 70.1 to 140.8 deg as a function of proton energy at the target ...

Abstract Even parity states in O 16 are studied using the shell model in the jj coupling scheme with a zero-range, spin-dependent residual interaction. This necessitates consideration of both one particle-one hole excitations through two oscillators shells and two particle-two hole excitations. The unperturbed energy spectrum is taken from data of

Abstract An approximate Hartree-Fock self-consistent-field calculation is carried out for the ground state of the O16 nucleus. The two-body interaction used has a finite hard core as well as tensor and Serber exchange interaction. Our zeroth-order wave function gives an improved ground state energy of −116.3 MeV as compared to −87.8 MeV obtained with

Cross sections for the O16(d, p0)O17, O16(d, p1O17∗ and O16(d, α0)N14 reactions from 0.8 to 1.7 MeV
Nuclear Physics, 1964Abstract Absolute cross sections for the O 16 (d, p 0 )O 17 , O 16 (d, p 1 )O 17∗ and O 16 (d, α 0 )N 14 reactions have been measured from 0.8 to 1.7 MeV at laboratory angles of 51.4°, 66.9°, 86.7°, 127.7°, 142.2° and 164.3°.

The search for putative precursor cells within the pancreas has been the focus of extensive research. Rare adult mouse pancreas-derived multipotent precursor (PMP) cells, possessing the intriguing capacity to generate cross-germ layer progeny in the pancreatic and neural lineages, have been identified.

Transitions au niveau 6.06 MeV des etats de O16 excites par N15(p, γ) O16
Physics Letters, 1963The branching ratios of (decay to 6.08-Mev level)/(decay directly to ground state) are measured for several 1/sup -/ states and one 11 state in O/sup 16/, namely, the levels at 13.1, 17.13, andd 17.3 Mev, and the level at 16.22 Mev, respectively. The results lead to the hypothesis of T = 1 for the 6.06-Mev level. (T.F.H.)

Paritätsverbotener Alpha-Zerfall in O16
Zeitschrift für Physik A Hadrons and nuclei, 1970The theory of the parity-nonconserving alpha-decays from levels in O16 is developed. Using the weak nucleon-nucleon interaction of Blin-Stoyle and Herczeg and known O16 wave-functions modified by short-range correlations via Bethe-Goldstone equation, the irregular alpha widths of the states 2−(8.88 MeV) and 3+(11.05 MeV) have been related to known ...
