Widths and Spectroscopic Factors in 21O
نویسندگان
چکیده
A recent 20O(d,p)21O experiment, in reverse kinematics, discovered two new states in 21O at 4.77(10) and 6.17(11) MeV, with Jπ assignments of 3/2+ and of 3/2+ or 7/2−, respectively. Both widths and spectroscopic factors were reported, along with the branching ratio for the upper state to decay to the 2+ state of 20O. We have computed single-particle widths for all the relevant decays and have used them to extract additional information for these two states, including the spectroscopic factors for 2+ decay of the upper state with the two possible Jπ values. Our analysis prefers 7/2− for Jπ. Disciplines Physical Sciences and Mathematics | Physics Comments Fortune, H. T. and Sherr, R. (2012). Widths and Spectroscopic Factors in 21O.

Case report: AID, a new principle of correction to treat proximal structural curve with a brace
Case report A 14 year old was diagnosed with AIS at 10 years of age. In a first X-ray from February 2010 it was noted a right thoracic curve measuring 7o Cobb, combined with a left lumbar measuring 7o Cobb. Proximal thoracic region was not measurable. One year later, February 2011 the Cobb angles progressed to 18o and 13o respectively, and progression was confirmed on September 2011 with a Cobb...
متن کاملVUV spectroscopic study of the state of H2
Spectral lines, probing rotational quantum states J′ = 0, 1, 2 of the inner well vibrations (v′ ≤ 8) in the B ′′B̄1 + u state of molecular hydrogen, were recorded in high resolution using a vacuum ultraviolet Fourier transform absorption spectrometer in the wavelength range 73–86 nm. Accurate line positions and predissociation widths are determined from a fit to the absorption spectra. Improved ...
متن کاملSpectral line variability amplitudes in AGNs ⋆ , ⋆ ⋆
We present the results of a long-term variability campaign of very broad-line AGNs with line widths broader than FWHM > 5000 kms −1. The main goal of our investigation was to study whether the widths of the optical broad emission lines are correlated with the optical intensity variations on timescales of years. Our AGN sample consisted of 10 objects. We detected a significant correlation betwee...
متن کاملA Search for “ Dwarf ” Seyfert Nuclei . III . Spectroscopic Parameters and Properties of the Host
We have completed an optical spectroscopic survey of the nuclear regions (r < ∼ 200 pc) of a large sample of nearby galaxies. Although the main objectives of the survey are to search for low-luminosity active galactic nuclei and to quantify their luminosity function, the database can be used for a variety of other purposes. This paper presents measurements of the spectroscopic parameters for th...
متن کاملThe identification of the star SPH 2 as a new WN 4 star with strong CIV ?
We report spectroscopic observations of a new WolfRayet star not identified yet. This star is located in our Galaxy, in the Canis Majoris region and was discovered during a southern spectroscopic survey of stars previously identified as Hα emission objects. The star, SPH 2, after Schwartz, Persson & Hamann (SPH) (1990), shows the main characteristics of a WN star and a strong CIV 5808 typical o...
