PREFACE
The second course of the International School on the Physics of
Exotic Atoms took place at the "Ettore Majorana" Center for Scien
tific Culture, Erice, Sicily, during the period from March 25 to
April 5, 1979. It was attended by 40 participants from 23 insti
tutes in 8 countries.
The purpose of the course was to review the various aspects of
the physics of exotic atoms, with particular emphasis on the re
sults obtained in the last two years, i.e., after the first course
of the School (Erice, April 24-30, 1977). The course dealt with
two main topics, A) Exotic atoms and fundamental interactions and
B) Applications to the study of the structure of matter.
One of the aims of the course was to offer an opportunity for
the exchange of experiences between scientists working in the two
fields. In view of this, the lectures in the morning discussed
the more general arguments in a common session, whereas the more
specialized topics were treated in the afternoon, in two parallel
sections.
Section A was organized around four main subjects, briefly pos
itronium and muonium, quarkonium, baryonium and neutral currents
in atomic physics. In addition various progresses were reported
in muon and antiproton physics.
In section B a comprehensive account of the field of muon spin
rotation was given. The topics covered were: muon motion in solids,
muons in semiconductors and ferromagnetic materials, isotope effects
of Hydrogen diffusion in metals, the chemistry of muonic radicals,
problems of site determination, muonium induced quadrupole moments,
muons in semimetals and quantum tunnelling.
The lecturers were kind enough to edit their notes so that we
are now able to present the proceedings of the course; we would
like to express our appreciation and gratitude to all of them for
the effort they put into both the preparation and presentation of
these lectures.
