New data acquisition system of the Lintott magnetic spectrometer at the S-DALINAC
M. Singer, U. Bonnes, A. D'Alessio +3
A new data acquisition system for the high resolution magnetic spectrometer Lintott at the superconducting Darmstadt electron linear accelerator S-DALINAC was developed. It allows…
Injection of Positrons into a Dense Electron Cloud in a Magnetic Dipole Trap
M. Singer, M. R. Stoneking, E. V. Stenson +7
The creation of an electron space charge in a dipole magnetic trap and the subsequent injection of positrons has been experimentally demonstrated. Positrons (5eV) were magnetically…
Electric and magnetic dipole strength in 112,114,116,118,120,124Sn
S. Bassauer, P. von Neumann-Cosel, P. -G. Reinhard +33
Inelastic proton scattering experiments were performed at the Research Center for Nuclear Physics, Osaka, with a 295 MeV beam covering laboratory angles 0°-6° and excitation ener…
Precision measurement of the transition strength to the 2 state of C
A. D'Alessio, T. Mongelli, M. Arnold +16
The form factor of the electromagnetic excitation of C to its 2 state was measured at extremely low momentum transfers in an electron scattering experiment at the S-DA…
CASTRO: A New Compressible Astrophysical Solver. I. Hydrodynamics and Self-Gravity
A. S. Almgren, V. E. Beckner, J. B. Bell +7
We present a new code, CASTRO, that solves the multicomponent compressible hydrodynamic equations for astrophysical flows including self-gravity, nuclear reactions and radiation. C…
First Measurement of Collectivity of Coexisting Shapes based on Type II Shell Evolution: The Case of Zr
C. Kremer, S. Aslanidou, S. Bassauer +13
Background: Type II shell evolution has recently been identified as a microscopic cause for nuclear shape coexistence. Purpose: Establish a low-lying rotational band in 96-Zr. Meth…
Extremal metrics on blow ups
C. Arezzo, F. Pacard, M. Singer
Given a compact Kahler manifold with an extremal metric (M,Ï), we give sufficient conditions on finite sets points p_1,...,p_n and weights a_1,...a_n for which the blow up of M at…
Evolution of the dipole polarizability in the stable tin isotope chain
S. Bassauer, P. von Neumann-Cosel, P. -G. Reinhard +36
The dipole polarizability of stable even-mass tin isotopes 112,114,116,118,120,124 was extracted from inelastic proton scattering experiments at 295 MeV under very forward angles p…
