Systematic study of Î(1232) resonance excitations using single isobaric charge-exchange reactions induced by medium-mass projectiles of Sn
J. L. Rodriguez-Sanchez, J. Benlliure, I. Vidana +26
The fragment separator FRS has been for the first time used to measure the (n,p) and (p,n)-type isobaric charge-exchange cross sections of stable 112,124Sn isotopes accelerated at…
The black hole mass vs bulge mass relationship in spiral galaxies
A. Marconi, D. Axon, J. Atkinson +15
We describe an on-going HST program aimed at determining the relationship between the nuclear black hole mass and bulge mass in spiral galaxies. We have selected a volume limited s…
Charge Pickup Reaction Cross Section for Neutron-Rich p-Shell Isotopes at 900A MeV
J. -C. Zhang, B. -H. Sun, I. Tanihata +34
We report charge pickup reaction cross sections for 24 \textit{p}-shell isotopes, including Li, Be, B, C and N, measured…
Nuclear Properties of Nearby Spiral Galaxies from Hubble Space Telescope NICMOS imaging and STIS Spectroscopy
M. A. Hughes, D. Axon, J. Atkinson +16
We investigate the central regions of 23 spiral galaxies using archival NICMOS imaging and STIS spectroscopy. The sample is taken from our program to determine the masses of centra…
Proton distribution radii of O: signatures of new shell closures and neutron skin
S. Kaur, R. Kanungo, W. Horiuchi +38
The root mean square radii of the proton density distribution in O derived from measurements of charge changing cross sections with a carbon target at 900 MeV to…
Neutron skin and signature of the = 14 shell gap found from measured proton radii of N
S. Bagchi, R. Kanungo, W. Horiuchi +37
A thick neutron skin emerges from the first determination of root mean square radii of the proton distributions for N from charge changing cross section measurements arou…
Proton distribution radii of C illuminate features of neutron halos
R. Kanungo, W. Horiuchi, G. Hagen +35
Proton radii of C densities derived from first accurate charge changing cross section measurements at 900 MeV with a carbon target are reported. A thick neutron surfac…
A new approach for deducing rms proton radii from charge-changing reactions of neutron-rich nuclei and the reaction-target dependence
J. -C. Zhang, B. -H. Sun, I. Tanihata +35
We report the charge-changing cross sections () of 24 -shell nuclides on both hydrogen and carbon at about 900 MeV, of which Li, $^{10\textendash12}$B…
An integrable multicomponent quad equation and its Lagrangian formulation
J. Atkinson, S. B. Lobb, F. W. Nijhoff
We present a hierarchy of discrete systems whose first members are the lattice modified Korteweg-de Vries equation, and the lattice modified Boussinesq equation. The N-th member in…
Study of excitations in medium-mass nuclei with peripheral heavy ion charge-exchange reactions
J. L. Rodriguez-Sanchez, J. Benlliure, I. Vidaña +26
Isobaric single charge-exchange reactions, changing nuclear charges by one unit but leaving the mass partitions unaffected, have been for the first time investigated by peripheral…
Is there really a Black Hole at the center of NGC 4041? - Constraints from gas kinematics
A. Marconi, D. J. Axon, A. Capetti +16
We present HST/STIS spectra of the Sbc spiral galaxy NGC 4041 which were used to map the velocity field of the gas in its nuclear region. We detect the presence of a compact (r~0.4…
Observation of Large Enhancement of Charge Exchange Cross Sections with Neutron-Rich Carbon Isotopes
I. Tanihata, S. Terashima, R. Kanungo +30
Production cross sections of nitrogen isotopes from high-energy carbon isotopes on hydrogen and carbon targets have been measured for the first time for a wide range of isotopes. T…
Nuclear properties of a sample of nearby spirals from STIS imaging
C. Scarlata, M. Stiavelli, M. Hughes +17
We present surface photometry for the central regions of a sample of 48 spiral galaxies (mostly unbarred and barred of types Sbc or Sc) observed with the Space Telescope Imaging Sp…
