Abstract Using the generator coordinate method to investigate the validity of the use of a potential to describe heavy ion elastic scattering, it is found that, under certain conditions, an effective potential exists. These conditions are generally satisfied by heavy ions, especially for the potential's tail. The potential obtained includes a kinetic

Inositides and the nucleus and inositides in the nucleus
Cell, 1993Although there are many forms of evidence linking phosphoinositides to nuclear function, the substance of the links remains largely undefined. One link between inositide metabolism and the nucleus is suggested by the implication of inositol trisphosphate (IP3) in the process of nuclear envelope reassembly (Sullivan et al., 1993).

Meson production in proton-nucleus and nucleus-nucleus collisions [PDF]
The production of K+ or q mesons in proton-nucleus reactions is analysed with respect to primary nucleon-nucleon (NN + NhK+ or NNq) and secondary pion-nucleon (nN + K+A or qN) production channels on the basis of a phase-space model employing Hartree-Fock groundstate momentum distributions and free on-shell production processes.

Beginning in the 1890s, Lenard investigated the attenuation of electron beams passing through matter. This attenuation can have two causes: the electrons can lose their energy by exciting or ionising atoms, or they can be elastically scattered and so change their directions and leave the beam.

Publisher Summary This chapter focuses on the nucleus of a cell, which is a large disklike, lobed, or spherical organelle of about 10 μm in diameter, the morphology of which depends on the activity of the cell. It contains the DNA of the cell and is surrounded by an envelope composed of two concentric membranes made up of lipids and proteins.

Nucleus-nucleus collision as superposition of nucleon-nucleus collisions
Nuclear Physics B - Proceedings Supplements, 1999Abstract Angular distributions of charged particles produced in 16O and 32S collisions with nuclear track emulsion were studied at momenta 4.5 and 200 A GeV/c. Comparison with the angular distributions of charged particles produced in proton-nucleus collisions at the same momentum allows to draw the conclusion, that the angular distributions in ...

Quark model for nucleus-nucleus collisions
Physical Review C, 1987We present a simple quark model for nucleus-nucleus collisions which employs the Glauber multiple scattering theory. The model is first used to fit a quark-quark scattering amplitude to high energy nucleon-nucleon elastic scattering data. This amplitude is then used to calculate high energy \ensuremath{\alpha}p and \ensuremath{\alpha}\ensuremath{\alpha}

Perspectives of ultrarelativistic nucleus-nucleus collisions
Progress in Particle and Nuclear Physics, 1985Abstract The lectures delivered at this school survey the expectations for the new field of ultrarelativistic nucleus-nucleus collisions. Nearly all the material covered is available in the literature. Therefore, only an extended abstract is reproduced in the following, containing the primary motivation for the field, the organization of the lectures,
