Influence of the nuclear charge distribution and electron correlation effects on magnetic shieldings and spin-rotation tensors of linear molecules

The origin and the size of both, electron correlation and nuclear charge distribution on shieldings and spin-rotations of heavy-atom containing linear molecules are shown. The analysis is performed on the relativistic and non relativistic regimes.

FRAGMENTATION OF RADIOACTIVE BEAMS FOR TAILORING FISSION TRANSIENTS

A novel experimental approach for studying dissipative effects in nuclear fission has been developed at GSI, Darmstadt. Fragmentation of radioactive heavy-ion beams is employed to prepare fissile nuclei in well-defined initial conditions and the fission-fragment nuclear charge distribution is used for investigating pre-saddle dynamics in detail. The undeniable manifestation of transient effects at high temperature is demonstrated and the influence of the initial deformation is clearly evidenced for the first time.

Lithium transition energies and isotopic shift: three correlated electron states

Energies of the 1s22s2S1/2 and the 1s23s2S1/2 of the lithium isotopes are calculated in a dynamic correlation model. With the evaluated configuration mixing wave functions the polarization effects resulting from an extended nuclear charge distribution are evaluated. A relative large contribution for 7Li is observed.PACS Nos.: 32.10.Fn, 21.10.Ft, 27.20.+n
