Coupled Collective Motion in Nuclear Reactions

In this paper, we review the roles of collective modes in nuclear reactions. We emphaize the strong couplings of various collective states with the monopole and quadrupole motions. In inelastic excitation, these couplings can be seen as an important source of anharmonicity in the multiphonon spectrum. In fusion reaction, the breathing and quadrupole motions strongly affects the oscillation of p...

The Study of Nuclear Collective Motion by Stripping Reactions*

The ‘intrinsic’ prohabilit,v for capt,ure of nurleons is studied for nurlei which exhibit collective vibrations or rotations in addition to an underlying shell structure of independent, nucleon orbits. Such probabilities or reduced widths for lowlying nuclear levels can be measured in ‘direct’ nuclear reactions; the present discussion is formulated chiefly in terms of deuteron stripping. Variou...

Does localization occur in collective nuclear motion?

Large-amplitude collective nuclear motion is frequently described by a collective Hamiltonian [1], where the mass parameter is determined within the cranking approximation while the potential energy is defined by the groundstate expectation value of the many-body Hamiltonian as function of the collective variable q. However, due to quasicrossings of levels the mass parameter exhibits large fluc...

Dominant collective motion in globally coupled tent maps

We investigate collective motion in high dimensional chaos, where all elements in a population behaves chaotically and incoherently in appearance. Numerical experiments for globally coupled tent maps show the existence of a quasi-periodic collective motion even under slight interaction. It is found that the amplitude of the collective motion F is scaled as, KF ∝ exp(−K−1), by the coupling stren...

On the Collective Motion in Globally Coupled Chaotic Systems

A mean–field formulation is used to investigate the bifurcation diagram for globally coupled tent maps by means of an analytical approach. It is shown that the period doubling sequence of the single site map induces a continuous family of periodic states in the coupled system. This type of collective motion breaks the ergodicity of the coupled map lattice. The stability analysis suggests that t...
