Die Winkelverteilung im Bereich 30 bis 155� von elastisch an Golddampf gestreuten Elektronen mit Energien zwischen 150 und 1900 eV
1963
The angular distribution of electrons scattered elastically by gold atoms has been investigated over the angular range from 30 to 155° and with electron energies between 150 and 1900 eV. The scattering curves obtained resemble closely the corresponding curves for mercury atoms. The theoretically expected energy dependence of the 90°-scattering is in poor agreement only with the results obtained experimentally in this work.
Elastische Streuung langsamer Elektronen an einem Bi-Atomstrahl
1968
The angular distribution of electrons elastically scattered by bismuth atoms has been investigated in the angular range from 30 to 155° and with electron energies between 5 and 1200 eV. Theoretical data, which are available for energies above 100 eV, are in good agreement with experiment.
Spinpolarisation langsamer Elektronen durch elastische Streuung an Edelgasatomstrahlen
1968
The angular dependence of spin polarisationP(θ) of electrons elastically scattered by noble gas atomic beams is measured in a double-scattering experiment for electron energies between 40 and 150 eV and over an angular range fromθ=30‡ toθ=150‡. Maximum degree of polarisation measured isP=+ 39.5%±2.6% (Xe; 150eV;θ=60‡). The results are compared with the theoretical values ofCoulthard, which agree approximately with the measurements only for Xenon. For all lower atomic numbers the experimental values are higher than the theoretical ones.
Winkelverteilung von elastisch und mit 6,7 eV-Energieverlust an freien Hg-Atomen gestreuten Elektronen
1970
The angular dependence of electrons scattered elastically and inelastically at free mercury atoms have been measured for electron energies between 20 and 300 eV (angular range from 20 to 155°).
Differentielle Wirkungsquerschnitte für die elastische Streuung niederenergetischer Elektronen an Kalium
1971
The elastic differential cross sections of electrons scattered by potassium has been measured over the angular range from 25 ° to 150 ° and with electron energies between 0.9 and 15 eV. The results are compared with other experimental data and with theoretical values. The agreement is only partly satisfactory.
Winkelverteilungen elastisch an Edelgas-Atomstrahlen gestreuter Elektronen; Spinpolarisation eines an Argon gestreuten 40 eV-Elektronenstrahls
1967
The angular distribution of electrons scattered elastically by rare-gas atomic beams (He, Ne, Ar, Kr, Xe) has been investigated over the angular range from 20° to 155° and with electron energies between 5 eV and 1000 eV. The results are compared with theory. Only for energies above 300 eV the agreement is good. The angular dependence of polarization P(Θ) of electrons, elastically scattered by a beam of argon atoms, is measured in a double scattering experiment for an electron energy of 40 eV. Maximum degree of polarization measured isP=12.5% ± 2.5%.
Spectroscopy of the neutron-deficient nuclide 171Pt
2003
A number of previously unobserved gamma-rays emitted from the neutron-deficient nuclide Pt-171 have been identified using the recoil decay tagging technique. The level scheme has been updated using ...
Beta-delayed neutrons and high-energy gamma-rays from decay of137I
1980
Beta-delayed neutrons and high-energyγ-rays following decay of137I have been studied in order to characterizeβ-decay to and deexcitation of neutron-unbound levels in137Xe. The totalγ-ray intensity observed accounts for at least 20% of theβ-intensity to levels aboveB n . No evidence was found for neutron andγ-ray emission from the same levels. With the experimentalβ-strength function aboveB n detailed tests were performed on the reproduction of the experimental neutron spectrum, the level density and Porter-Thomas fluctuations of the reducedβ-transition probabilities to highly excited states in137Xe.
Structure of the highly deformed nucleus101Sr63 and evidence for identical K=3/2 bands
1995
The low-energy level scheme of theN=63 nucleus101Sr has been obtained from a β-decay study of101Rb. The ν[532]5/2 and ν[411]3/2 orbitals are well established as the ground state and a band head at 271.2keV, respectively. The general properties of the level scheme indicate a quadrupole deformation ofβ ≃ 0.4, confirming the unique feature of saturation of deformation inN ≥ 60 Sr isotopes. The energies of theK=3/2 intraband transitions in the odd-neutron neighbours99Sr61 and101Sr63 are very similar. More generally, the identical bands at low spin in98–101Sr nuclei are correlated with the mass-independent moments of inertia in this region.
K-isomeric state in even-even100Sr
1995
A t1/2=85 ns isomer has been identified at 1619 keV in100Sr. The halflife is attributed to a ΔK=4 hindered decay. The configuration is proposed to be built on the [411]3/2 and the [532]5/2 neutron quasiparticle orbitals.
