The Impact

Calculations with the fission model GEF are performed over an extended region in fissioning-system mass A, charge Z, excitation energy E∗ and angular momentum L. The present contribution focuses on fission-fragment mass and isotopic distributions, benefiting from recent innovative measurements. The influence of the system (A, Z, E∗, L) properties and of multi-chance fission is studied. The impact of accurate experimental knowledge about these properties and instrumental resolution is discussed. The need of as selective and accurate as possible experimental data to improve the model is demonstrated.

Structure Investigations

As a subset of radioactive beams, isomer beams open up the dimensions of excitation energy and angular momentum. The problem of isomer decay rates is briefly presented, as they are not yet well understood. The use of isomer beams for nuclear structure investigations is reviewed, using examples related to exotic decay modes, charge radii, and Coulomb excitation. There are also unique possibilities for the study of induced electromagnetic depopulation. A key aspect is beam purification, for which different techniques are discussed.

1. There seems to be little doubt that the detailed mechanism of ionisation or excitation by electron impact will not admit of description, even to a first approximation, by the system of classical mechanics. However the experimental work of Franck and Horton and their collaborators, has shown that, within the limits of the error of experiment, an electron is able to impart the whole or part of its kinetic energy to the atom it excites. When its initial energy is greater than the excitation energy, the electron, instead of being brought to rest, retains the excess as kinetic energy.
