A nonperturbative solution to the Dyson-Schwinger equations of QCD
Springer Science and Business Media LLC - Tập 336 - Trang 423-433 - 1990
U. Häbel, R. Könning, H. -G. Reusch, M. Stingl, S. Wigard
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 n g 2n Γ( n ) where eachΓ( n ) approaches its perturbative form at large momenta. At lower momenta, it differs from that ...... hiện toàn bộ
Physikalische Vorgänge bei elektrischen Drahtexplosionen
Springer 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/u
Springer Science and Business Media LLC - Tập 326 - Trang 235-236 - 1987
H. Tsertos, F. Bosch, P. Kienle, W. Koenig, C. Kozhuharov, E. Berdermann, S. Huchler, W. Wagner
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 Theory
Springer 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 in188Hg
Springer Science and Business Media LLC - Tập 313 - Trang 289-292 - 1983
H. Sergolle, P. Aguer, G. Bastin, R. Kroth, J. P. Thibaud, K. Hardt, T. Lönnroth, F. Beck, J. C. Merdinger
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.
Erratum to: Theory of coupled mode oscillation in a laser with axial magnetic field
Springer Science and Business Media LLC - Tập 211 - Trang 418-418 - 1968
H. Pelikan
A unique parameterization for the transition potential in muonic x-rays
Springer Science and Business Media LLC - Tập 289 - Trang 391-394 - 1979
S. S. Wald, Asok Ray, Y. N. Kim
A single-parameter form approximating the transition potential in muonic atoms is presented. The single-parameter form yields comparable results with that obtained by the Barrett form in radial moment analysis. The single parameter,β, is isotopically independent and is uniquely defined by the particular transition of a given element.
Measurement of spin-dependent total cross-section difference Δσ L in neutron-proton scattering at 16 MeV
Springer Science and Business Media LLC - - 1997
Jan Brož, J. Černý, Z. Doležal, G. M. Gurevich, M Jirásek, P. Kubík, A.A. Lukhanin, Jan Taro Svejda, I. Wilhelm, N. S. Borisov, Yu.M. Kazarinov, B. Khachaturov, E. S. Kuzmin, V.N. Matafonov, A. Neganov, I. L. Pisarev, Yu. A. Plis, Yu. A. Usov, M. Rotter, B. Sedlák
Phase transitions in fermionic systems with many-body interactions
Springer Science and Business Media LLC - Tập 333 - Trang 119-123 - 1989
G. Bozzolo, A. Plastino, J. Ferrante
A linearized version of the Hartree-Fock method is used as a probe to investigate phase transitions in fermionic systems with many-body interactions. An application to a new exactly solvable model which includes two- and three-body forces is shown.
Lifetime-measurements of alkali-molecules excited by different laserlines
Springer Science and Business Media LLC - Tập 232 - Trang 462-472 - 1970
G. Baumgartner, W. Demtröder, M. Stock
Absorbing different lines of acw-argon ion laser or a He-Ne-laser the alkali molecules Na2, K2, Rb2 and Cs2 can be pumped into different rotational-vibrational levels of an excited electronic state. The lifetimes of these states have been measured using the phase shift technique at a modulation frequency of 18 Mc/sec. Because of collisions with the always present alkali atoms the excited molecules...... hiện toàn bộ
