The purpose of this monograph is to describe a microscopic nuclear
theory which can be used to consider all low-energy nuclear phenomena
from a unified viewpoint. In this theory, the Pauli principle is
completely taken into account and translation ally invariant wave
functions are always employed. Also, this theory is quite flexible; it
can be utilized to study reactions initiated not only by nucleons but
also by arbitrary composite particles. Throughout this monograph, we
have endeavoured to keep the underlying physical ideas as easily
comprehensible as possible. Consequently, it becomes frequently
necessary to sacrifice mathematical rigour in favour of clarity in
presenting these ideas. In this way, it is our hope that this monograph
could be useful to many research physicists in the nuclear field,
experimentalists and theorists alike. In chapters 1 through 4, the
formulation of this theory is presented. Numerical examples concerning
bound-state, scattering, and reaction calculations are mainly described
in chapters 5 through 7. In chapters 8 through IS we discuss, within the
framework of this theory, general properties of nuclear systems.
Finally, in chapters 16 and 17, we show in specific cases how one can
achieve, without carrying out explicit calculations, a qualitative or
even semi-quantitative understanding of these cases by applying the
general physical concepts contained inherently in this theory.
