Measuring the proton spectrum in neutron decay - latest results with aSPECT
M. Simson, F. Ayala Guardia, S. Baeßler +11
The retardation spectrometer aSPECT was built to measure the shape of the proton spectrum in free neutron decay with high precision. This allows us to determine the antineutrino el…
New supersymmetric quartet of nuclei in the A=190 mass region
J. Barea, R. Bijker, A. Frank +10
We present evidence for a new supersymmetric quartet in the A=190 region of the nuclear mass table. New experimental information on transfer and neutron capture reactions to the od…
Q-Value for the Fermi Beta-Decay of 46V
T. Faestermann, R. Hertenberger, H. -F. Wirth +3
By comparing the Q-values for the 46Ti(3He,t)46V and 47Ti(3He,t)47}V reactions to the isobaric analog states the Q-value for the superallowed Fermi-decay of 46V has been determined…
Role of cross-shell excitations in the reaction 54Fe(d_pol,p)55Fe
M. Mahgoub, R. Kruecken, Th. Faestermann +6
The reaction 54Fe(d_pol,p)55Fe was studied at the Munich Q3D spectrograph with a 14 MeV polarized deuteron beam. Excitation energies, angular distributions and analyzing powers wer…
New supersymmetric quartet of nuclei: 192Os, 193Os, 193Ir, 194Ir
R. Bijker, J. Barea, A. Frank +4
We present evidence of the existence of a new supersymmetric quartet of nuclei in the A=190 mass region. The analysis is based on new experimental information on the odd-odd nucleu…
Accumulation and extraction of ultracold neutrons from a superfluid helium converter coated with fluorinated grease
O. Zimmer, P. Schmidt-Wellenburg, M. Assmann +5
We report experiments on the production of ultracold neutrons (UCN) in a converter of superfluid helium coated with fluorinated grease. We employed our technique of window-free ext…
