Nuclear kinematics

In many cases there are dynamics involving the coupling of states, examples including nuclear kinematic (nonadiabatic), optical, and spin-orbit... 

For the electro-nuclear model, it is the charge the only homogeneous element between electron and nuclear states. The electronic part corresponds to fermion states, each one represented by a 2-spinor and a space part. Thus, it has always been natural to use the Coulomb Hamiltonian Hc(q,Q) as an entity to work with. The operator includes the electronic kinetic energy (Ke) and all electrostatic interaction operators (Vee + VeN + Vnn)- In fact this is a key operator for describing molecular physics events [1-3]. Let us consider the electronic space problem first exact solutions exist for this problem the wavefunctions are defined as /(q) do not mix up these functions with the previous electro-nuclear wavefunctions. At this level. He and S (total electronic spin operator) commute the spin operator appears in the kinematic operator V and H commute with the total angular momentum J=L+S in the I-ffame L is the total orbital angular momentum, the system is referred to a unique origin. 

So the thick target-thick catcher method can lead to crude information about the kinematics of the nuclear reaction under study (Harvey, 1960). This technique can be used to advantage in the study of intermediate energy and relativistic nuclear collisions where the energy of the heavy residues is low ( 10-100 keV/ nucleon). In this case, most of the residues stop in the target foil and cannot be studied any other way.1... 

Finally, we would like to point out that the kinematic effects of DCF inducing an asymmetry in mass balance in a many-body system should be of universal significance not only in molecular systems but also in a wide variety of many-body systems. This is because the DCF originates not from the interaction potential but from the intrinsic metric of internal space, which is uniquely determined from the shape and mass balance of a system. It is therefore anticipated that the DCF should be an important factor not only in molecular dynamics but in collective motions in nuclear, celestial, and biological many-body systems. 

Neutrons are particles liberated in fission of in nuclear reactors or by pelting heavy nuclei with GeV protons in spallation sources. They propagate with a finite velocity v. and according to the laws of kinematics, a neutron with mass rn= 1.675 g has a kinetic energy... 

We have also demonstrated the capabilities of eFF for computing single-shock Hugoniots for lithium metal from dynamic shock wave experiments, via the shock wave and piston kinematics and initial and final densities of a 640,000-particle system (see Fig. 10). We also reported on the degree of ionization suffered by the material, a function of the explicit nuclear delocalization of electrons [90]. A simpler depiction of such dynamic shock experiments is shown in Fig. 11, wherein... 

Measurements of production cross sections are performed with a wide range of both radiochemical and direct counter techniques. Historically, radiochemical techniques were particularly useful for measuring heavy residues, for which discrete Z and A identification are difficult to determine with nuclear particle detectors in reactions with normal kinematics. However, with the availability of very heavy-ion beams and the widespread use of reverse kinematics, the measurement of mass (dcr dA), charge (dcr dZ), and isotope (dheavy residues, these values are frequently summarized graphically in terms of an excitation function, or cross section as a function of projectile energy, as in O Fig. 3.11. Extensive listings of production cross sections are maintained in several databases (IAEA 2010 NEA 2010 NNDC 2010 RNDC 2003).
