Experimental and theoretical papers of both a fundamental and applied nature that contribute to the understanding of either phenomena induced by the interaction of radiation with condensed matter or defects in solids introduced not only by radiation but also by other processes are published in three groups. Section A: Radiation Effects - Suitable topics include, but are not limited to, atomic collisions, radiation induced atomic and molecular processes in solids, the stopping and range of ions and radiation damage, sputtering and mixing in solids, radiation-induced transport phenomena and the role of defects and impurities introduced by radiation. Papers on ion implantation in metals and semiconductors; radiation effects in insulators, biomatter, superconductors, fusion and fission devices and space research; as well as fission tracks, isotope dating, ion beam analytic techniques and applications of ion irradiation and ion tracks are also welcome. Section B: Crystal Lattice Defects and Amorphous Materials ÷ Topics covered include atomic and electronic properties of defects, the influence of defects on lattice properties and processes, the lattice-defect approach to solid state reactions such as clustering, precipitation, laser annealing and the role of impurities, the defect dynamics in a non-steady state such as under particle or electromagnetic irradiation or during a rapid temperature change and problems associated with the metastable nature of amorphous materials. NEW Section C: Biological Applications ÷ Contributions from the fields of fundamental and applied radiobiology are invited for our new Biological Applications Section. Topics will include tumour radio-therapy and fundamental research in radiative cell degeneration.
