Droplet model nuclear density distributions and single-particle potential wells

Single Particle and Collective Spin Excitations in Semimagnetic Quantum Wells

Collective and single-particle spin-flip excitations of a two-dimensional electron gas in a semimagnetic Cd1−xMnxTe quantum well are observed by resonant Raman scattering. Application of a magnetic field splits the spin-subbands and a spin-polarization is induced in the electron gas. Above some critical field, a collective spin-flip mode, which disperses with in-plane wave vector, dominates the...

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions

By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

1 9 Ja n 20 10 Nuclear single - particle states : dynamical shell model and energy density functional methods

We discuss different approaches to the problem of reproducing the observed features of nuclear single-particle (s.p.) spectra. In particular, we analyze the dominant energy peaks, and the single-particle strength fragmentation, using the example of neutron states in Pb. Our main emphasis is the interpretation of that fragmentation as due to particle-vibration coupling (PVC). We compare with rec...

Nuclear Gluon Distributions in a Parton Model

Gluon distributions in the carbon and tin nuclei are investigated by using a Q 2 rescaling model with parton recombination effects. We obtain strong shadowings in the small x region due to the recombinations. The ratio G A (x)/G N (x) in the medium x region is typically 0.9 for medium size nuclei. At large x, the ratio becomes large due to gluon fusions from different nucleons. Comparisons with...
