Coulomb energies of spherical nuclei
(Elsevier, 1972-02-14)
A phenomenological Coulomb energy equation has been derived for spherical nuclei with diffuse surfaces. Contributions from the direct and exchange Coulomb energy and from the electromagnetic spin-orbit interaction are ...
Studying gluon properties experimentally
(Elsevier, 1978-05-22)
We argue in this paper the following. (i) A large part of what is observed in high-energy hadron reactions may be rather directly interpretable in terms of gluon interactions. Since gluons do not interact directly with ...
On the optimization of the capacitive beam pick-off
(Elsevier, 1974-05-15)
Tests with the capacitive pick-off used with a time-of-flight system are described, and the optimization of the parameters is discussed.
Diffraction dissociation and Coulomb dissociation of high-energy neutrons by nuclei
(Elsevier, 1974-07-25)
We present the results of a spark chamber experiment in which we studied the reaction n + A --> (p + [pi]-) + A', where the (p[pi]-) pair is coherently produced off carbon, copper, and lead nuclei. Between 5 000 and 55 ...
Neutron-proton charge-exchange scattering from 8 to 29 GeV/c
(Elsevier, 1975-01-06)
The differential cross sections for neutron-proton charge-exchange scattering have been measured for incident neutron momenta between 8 and 29 GeV/c and for four-momentum transfers |t| between 0.002 and 1.0 (GeV/c)2. A ...
On the structure of high-energy two-body non-diffractive reactions
(Elsevier, 1970-10-15)
We consider the structure of two-body scattering amplitudes, concentrating on those reactions in which the "internal" quantum numbers exchanged correspond to the quantum numbers of a single particle, different from those ...
Search for a coupling scheme in heavy deformed nuclei: The pseudo SU(3) model
(Elsevier, 1973-03-05)
To test the possible usefulness of the pseudo SU(3) coupling scheme a few nuclear properties are examined which can be expected to be governed largely by the (1g2d2d3s) part of the proton configuration for odd-Z nuclei and ...
Five-dimensional quasispin toward a complete classification of the isospin characteristics of shell-model states in the seniority scheme
(Elsevier, 1970-04-27)
A solution is proposed for the inner multiplicity problem associated with the five-dimensional quasispin description of shell-model states. A classification scheme, in terms of an orthonormal basis, leads to tractable ...
Spectral distributions and the breaking of isospin and supermultiplet symmetries in nuclei
(Elsevier, 1974-04-29)
Knowledge of the Racah algebra for the higher unitary groups is exploited to give a general formula for the partial widths for the direct product subgroup U(N/k) x U(k) of the full unitary group U(N) of a given shell model ...
A model for charged second class currents
(Elsevier, 1976-10-25)
Choosing a model for the second class axial current composed of an s-wave vector current pseudoscalar meson pair to fix commutation relations, and using vector dominance (B-meson) techniques to calculate, we use recent ...
