      The shell model is generally considered the fundamental nuclear model and works best for light nuclei. More fundamental to the shell model's central position in nuclear physics is that it provides a well-defined procedure for the calculation of basic nuclear observables. However, the use of the shell model is, in practice, rather severely ://:oso//. Abstract. We review recent studies of the evolution of collective excitations in atomic nuclei far from the valley of β-stability. Collective degrees of freedom govern essential aspects of nuclear structure, and for several decades the study of collective modes such as rotations and vibrations has played a vital role in our understanding of complex properties of :// P/abstract.

    This book is written with a focus on new mathematical methods and physical modeling that lay the groundwork for an interpretation to various experimental results and phenomena in nuclear physics, quantum mechanics, and particle physics. Summarized in thre A long-time objective of nuclear structure physics has been to bridge the gap between collective and shell-model descriptions of observed nuclear phenomena. Progress has been slow because of the difficulty in making realistic shell-model calculations, and quite frankly, the success of the much simpler collective ://
