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...
متن کاملCoupled 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...
متن کاملEffects of Rotational Motion in Robotic Needle Insertion
Background: Robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations.Objective: In this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diagram. Non-homogenous camel liver can be exploite...
متن کاملCollective Reorientational Motion and Nuclear Spin Relaxation in Proteins
Significant progress in NMR methodology for measuring spin-relaxation data at many different 15N and 13C sites in proteins demands new and increasingly sophisticated ways of data interpretation. Recent work of our group concerning the use of anisotropic and reorientational collective motional models for spin-relaxation interpretation is briefly reviewed and a number of important aspects of coll...
متن کاملCharacter of Dissipation in Large Amplitude Collective Nuclear Motion
Within the Feynman Vernon path integral formalism and in the Markovian limit we consider the time evolution of a collective subsystem coupled to a bath of intrinsic degrees of freedom We show that dissipation leads to major qualitative and quantitative modi cations of the time evolution of the density matrix of the collective subsystem In either the spatial momentumor energy representation the ...
