Sp(4, R) symmetry in light nuclei
(Elsevier, 1980-08-11)
A classification of nuclear states according to the non-compact Lie algebra Sp(4, R) is investigated. This model strikes a compromise between the Sp(6, R) and Sp(2, R) models and furnishes a practical, yet algebraically ...
A possible new signature for Higgs bosons
(Elsevier, 1987)
If low-energy supersymmetry is realized in nature, and if the appropriate supersymmetric partner of the Higgs boson, , has a mass , then there is a decay chain , followed by , which can be a significant part of all Z decays, ...
Reaction dependence of nuclear decay linewidths
(Elsevier, 1981-08-17)
Various light- and heavy-ion reactions, 20 E 8Be*(2 + , 2.9 MeV) and 16O*(1-, 9.6 MeV). Although slight differences (R) are self-consistent and indicate little if any reaction dependence (R by 20 % or more, however, and ...
Interaction kernels for A = 4n binary cluster systems
(Elsevier, 1982-06-07)
Bargmann transform techniques used to calculate norm kernels for nuclear cluster systems have been generalized to evaluate interaction kernels for central interactions of gaussian form for binary cluster systems made up ...
The NN interaction in a quark model with quark-antiquark excitations
(Elsevier, 1985-11-11)
Quark-antiquark excitations inherent in the quark-gluon interaction have been incorporated into a quark model of the nucleon to study the effects of such excitations on the NN interaction within the framework of the ...
Band crossing and the prealignment B(E2) anomaly in 126Ba
(Elsevier, 1981-07-20)
A theoretical interpretation of the reduction in E2 strengths in 126Ba prior to backbending is presented. A shell model basis is built from normal parity orbilals organized into multiplets of a pseudo SU(3) symmetry coupled ...
The sub-Coulomb 12C + 12C resonances in a microscopic 12C+12C,[alpha]+20Ne, 8Be+16O cluster basis
(Elsevier, 1982-10-18)
The low-J resonances in the Coulomb barrier region of the 12 C+12C system are investigated in the framework of a microscopic cluster model basis including 12C+12C, [alpha]+ 20Ne, and su8 Be+ 16O fragment decompositions. ...
The NN interaction in a quark model with quark-antiquark excitations
(Elsevier, 1987-02-16)
The and excitations generated by off-shell terms of a Breit quark-gluon interaction are explicitly incorporated into the quark model of the NN system. Coupled channel RGM solutions lead to a semiquantitative zero ...
Isobaric analog states in rare-earth nuclei studied with the (3He, t) charge-exchange reaction at [theta]L = 0[deg]
(Elsevier, 1983-02-14)
The (3He, t) charge-exchange reaction leading to the ground-state isobaric analog states (IAS) of 152, 154, 156, 158, 160Gd, 160,162Dy, 162,164,166,168,170Er, 170, 172, 174, 176Yb and 176, 178, 180Hf has been studied at ...
Coherent-state theory for the LST quasispin group
(Elsevier, 1985-10-28)
An extended coherent-state theory is used to give a simple construction for the matrix elements of the L = 0 pair operators of the LST SO(8) [superset or implies] U(4) quasispin algebra leading to a more explicit construction ...
