With a summation-free β+-endpoint spectrometer the β+-decay energies of104Sn,147Tb,148, 149Dy,149Ho,150Er, and151Tm were remeasured with improved accuracy. Combined with known proton and alpha decay energies, the resulting QEC values lead to atomic masses of very neutron-deficient isotopes including nuclei beyond the proton drip-line such as109I and113Cs. Furthermore, the Gamow-Tellerβ-strength of...... hiện toàn bộ
A nonperturbative solution to the Dyson-Schwinger equations of QCDSpringer Science and Business Media LLC - Tập 336 - Trang 423-433 - 1990

This is the first of two papers in which we discuss a nonperturbatively modified solution to the Euclidean Dyson-Schwinger equations for the 7 superficially divergent proper verticesΓ of QCD. It takes the formΣ

Physikalische Vorgänge bei elektrischen DrahtexplosionenSpringer Science and Business Media LLC - Tập 150 - Trang 162-171 - 1958
Erwin David
Ein typisches Beispiel einer mittelstarken Drahtexplosion wird zwecks Klarstellung der verschiedenen, dabei nacheinander ablaufenden physikalischen Vorgänge durchgerechnet. — Der Strom von einigen kA heizt in reichlich 10−7 sec das Material des Drahtes auf fast 10000° auf. Trägheitskräfte, anfangs unterstützt durch magnetische Kräfte, halten es dabei nahezu an Ort und Stelle. Der Druck steigt in d...... hiện toàn bộ
Multiple positron structures observed from U-U collisions at 5.6 MeV/u and 5.9 MeV/uSpringer Science and Business Media LLC - Tập 326 - Trang 235-236 - 1987

High resolution positron spectroscopy in U-U collisions at bombarding energies of 5.6 MeV/u, the lowest energy studied until now as well as of 5.9 MeV/u, reveals similar multiple structures between 220 keV and 385 keV superimposed on the induced and nuclear continua.
Bag Scattering TheorySpringer Science and Business Media LLC - Tập 325 - Trang 275-279 - 1986
S. Noguera, V. Sanjosé, V. Vento
We reanalyze the procedure used thus far for the study of collision processes in the Chiral Bag Model from the point of view of scattering theory. In the present formalism thein andout states are free waves with no memory of the cavity. This feature gives rise to an observable effect consisting in a peculiar momentum dependence of the scattering amplitudes, which differs from that of previous calc...... hiện toàn bộ
The g-factor of the Jπ=12+ isomeric state in188HgSpringer Science and Business Media LLC - Tập 313 - Trang 289-292 - 1983

Using the reaction175Lu(19F, 6n) theg-factor of the188Hg isomeric state (J
π=12+,T
1/2=135 ns) has been measured with the TDPAD method. The experimental value g=−0.168(10) supports the interpretation of an almost pure (vi13/2)−2 configuration for this isomer.
Dissipative diabatic dynamics of nucleus-nucleus collisionsSpringer Science and Business Media LLC - Tập 326 - Trang 79-87 - 1987
A. Lukasiak, W. Nörenberg
First numerical studies of the time-dependence of central nucleus-nucleus collisions within the dissipative diabatic approach are presented. Effects from the non-markovian behaviour of dissipation, i.e., from the partially elastic response are illustrated and discussed for40Ca +40Ca and90Zr +90Zr at various incident energies. In particular, the probability for the emission of precompound giant qua...... hiện toàn bộ
