Foreword
It is apparent from the history of science, that few-body problems have an interdis
ciplinary character. Newton, after solving the two-body problem so brilliantly, tried his
hand at the Sun-Earth-Moon system. Here he failed in two respects: neither was he able
to compute the motion of the moon accurately, nor did he understand the reason for that.
It took a long time to understand the fundamental importance of Newton's failure,
and only Poincare realised what was the fundamental difficulty in Newtons programme.
Nowadays, the term deterministic chaos is associated with this problem.
The deep insights of Poincare were neglected by the founding fathers of Quantum
Physics. Thus history was repeated by Bohr and his students. After quantising the
hydrogen atom, they soon found that the textbook case of a three-body problem in atomic
physics, the 3He-atom, did not yield to the Bohr-Sommerfeld quantisation methods. Only
these days do people realise what precisely were the difficulties connected to this semi
classical way of treating quantum systems.
Our field, as we know it today, began in principle in the early 1950's, when Watson
sketched the outlines of three-body scattering theory. Mathematical rigour was achieved
by Faddeev and thereafter, at the beginning of the 1960's, the quantum three-body prob
lem, at least as far as short-range forces were concerned, w&s tamed.
In the years that followed, through the work of others, who first applied Faddeev's
methods, but later added new techniques, the three- and four-body problems became fully
housebroken.
In this process of domestication of few-body problems, mathematical techniques were
developed to handle systems in which long-range forces play an essential role, thus in
cluding atomic and molecular physics in our field.
These developments were strongly stimulated by the boom in computer hardware,
that took place simultaneously. The importance of the availability of powerful computers
cannot be overrated in our field, because the physics we are after manifests itself most
often in tiny effects. The circumstance that the basic dynamical equations governing the
behaviour of few-body systems are exactly soluble, enables us to concentrate fully on
the physics. Any discrepancy that may arise between the results of calculations and the
experimental data, barring simple mistakes on either side of course, must be due to an
incorrect or incomplete treatment of the dynamics of the systems we are concerned with.
We see a technology push, both in theoretical and experimental few-body physics.
Because the theoreticians claimed to be able to calculate physical observables to great
precision, experimentalists deemed it worthwhile to check their predictions accurately.
The interplay of theoretical and experimental approaches to few-body problems has led
to the present situation where accurate calculations are compared with ever more inge
nious experiments, involving for instance spin degrees of freedom and very small cross
sections. These experiments were made feasible by the great progress we have witnessed
in accelerator, beam and detector techniques.
The Fourteenth European Conference on Few-Body Problems in Physics was held in
Amsterdam, at the Trippenhuis, the seat of the Royal Netherlands Academy of Arts and
Sciences during August 23-27, 1993.
The previous European conferences of the series took place in Budapest (1972), Graz
(1973), Tiibingen (1975), Vlieland (1976), Uppsala (1977), Dubna (1979), Sesimbra (1980),
VIII
Ferrara (1981), Tbilisi (1984), Balatonfiired (1985), Fontevraud (1987), Uzhgorod (1990)
and Elba (1991).
The conference was divided into sixteen plenary sessions, four parallel sessions and
two presentations of posters.
This volume contains the invited talks but two, all of the contributed papers presented
at either the plenary sessions or the parallel sessions.
Many people and institutions have contributed to the organisation of the conference
and the preparation of the proceedings. We thank the Royal Academy of Arts and Sciences
of The Netherlands, Amsterdam, NIKHEF, Amsterdam, the Free University, Amsterdam,
KVI Groningen, the University of Groningen, the University of Nijmegen, FOM, Utrecht,
Utrecht University, Stichting Physica, Utrecht and Sun Microsystems Nederland B.V.
Amersfoort, for their generous financial support.
The main social event, a lecture by prof. dr. E. van de Wetering on the "Rembrandt
Project" , followed by a tour of the Gallery of Honour of the Rijksmuseum, was sponsored
by the Mayor and City Council of Amsterdam, for which we are very greatful.
Our thanks are also extended to the members of the International Advisory Committee
for their advise, to the chairmen of the sessions who kept the discussions in time and to
the speakers who send us their manuscripts before the deadline.
We are indebted to those people who helped us before, during and after the conference
to smooth out the difficulties we encountered. In particularly we want to mention Ms H.
Hogerhuis, who made our stay at the Trippenhuis so enjoyable, and Yvonne van der
Wensch and Elise de Wit, the conference secretaries.
Finally, the editors of the proceedings wish to thank W.J.W. Geurts and L.P Kok for
their help in preparing several parts of the manuscripts for the proceedings.
