Preface

The 26th International Conference on the Applications of the Mossbauer Effect(ICAME200 1) was held from 2nd to 7th September 2001 in Oxford.The Conference was attended by 290 participants who contributed the 215 manuscriptspublished in Hyperfine interactions and in Hyperfine Interactions (C).

An extensive program of invited presentations included talks on the vibrational density ofstates in Myoglobin, magnetic multi layers, ball-milling products, synchrotron studies,high pressure phenomena, spin transitions in polymeric compounds, extra-terrestrialplanetary surfaces and the current status of the gamma-ray laser.Contributed presentations were grouped into Advances in techniques, Amorphous, nano­crystalline and small particle systems, Applications in magnetism and lattice dynamics,Biological and medical applications, Chemical applications: structure and bonding, Earthscience, Mineralogy and archaeology, Industrial applications, catalysis and corrosion,Materials science and metallurgy and Surfaces, interfaces, thin films and multilayers.

In his closing remarks, Guido Langouche said that while Mossbauer Spectroscopy ismore and more just one of the techniques available in materials science, it remains anextremely powerful tool for magnetism studies. There were presentations in which,among the results of a number of complementary techniques it was the Mossbauer datathat was the key to understanding the problem . The new growth area is Synchrotronstudies, possibly open to only a minority of experimenters, which promised excitingresults in new resonances, holography and studies of phonon densities of states .

The organizers wish to acknowledge the following institutions and organizations thathave provided financial support to ICAME2001The University of LiverpoolThe Open UniversityThe University ofWolverhamptonThe Royal Society of Chemistry: Mossbauer Spectroscopy Discussion GroupUltra-Physics Limited

The organizers wish to thank the staff of the Institute of Physics for all their work in theadministering and running of this Conference.

The Proceedings Editors wish to thank the many participants who cheerfully and expertlyrefereed the many manuscripts.We would like to extend particular thanks to the Editorial Co-coordinator, JulieWardman, for her efficiency and humour in keeping track of all contributions.
