Systematic Extraction of Spectroscopic Factors
Past measurements of the angular distributions for the C(d,p)C and C(p,d)C reactions leading to the ground state have been analyzed systematically using the theory of distorted-wave Born-approximation (DWBA). By fitting the first peak of the angular distributions and developing a consistent set of input parameters to the DWBA calculations including the global parameterizations of optical model ...
متن کاملAccurate spectroscopic parameters of WASP planet host stars ⋆
We have made a detailed spectral analysis of eleven Wide Angle Search for Planets (WASP) planet host stars using high signal-to-noise (S/N) HARPS spectra. Our line list was carefully selected from the spectra of the Sun and Procyon, and we made a critical evaluation of the atomic data. The spectral lines were measured using equivalent widths. The procedures were tested on the Sun and Procyon pr...
متن کاملSolar and stellar measurements using accurate spectroscopic techniques
We propose to use low-cost optics equipment in order to (1) generate a Hertzsprung-Russell diagram for the 24 brightest stars visible in Beaumont, (2) analyze the polarization of stellar and solar light and the effect a telescope's optics have on these measurements, and (3) analyze the absorption spectrum due to Earth’s atmosphere on the Sun’s blackbody radiation spectrum.
متن کاملOn the meaning and usefulness of spectroscopic factors (Contribution to a panel discussion on spectroscopic factors)
This part of the discussion would like to review the concept of spectroscopic factors and how they relate to measured cross sections and nuclear correlations. A profound knowledge of how correlations affect the spectral function can help to better understand transfer reactions. Nowadays, we have a fairly complete picture for protons in stable nuclei but a lot remain to be learned regarding exot...
متن کاملWidths and Spectroscopic Factors in 21O
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 u...
