Van Orden Articles Published in Earlier Volumes ixThis volume contains two major articles, one providing a historical retrospective of one of the great triumphs of nuclear physics in the twentieth century and the other providing a didactic introduction to one of the quantitative tools for understanding strong interactions in the twenty-first century.The article by Igal Talmi on "Fifty Years of the Shell Model -the Quest for the Effective Interaction", pertains to a model that has dominated nuclear physics since its infancy and that developed with astonishing results over the next five decades. Talmi is uniquely positioned to trace the history of the Shell Model. He was active in developing the ideas at the shell model's inception, he has been central in most of the subsequent initiatives which expanded, clarified and applied the shell model and he has remained active in the field to the present time. Wisely, he has chosen to restrict his review to the dominating issue: the choice of the effective interactions among valence nucleons that determine the properties of low lying nuclear energy levels.The treatment of the subject is both bold and novel for our series. The ideas pertaining to the effective interaction for the shell model are elucidated in a historical sequence. In a massive article, which will be valued both for its completeness and its sound judgment of the various contributions to the subject, Talmi succeeds without use of a single figure comparing model results with each other or with experimental data. Instead, the compelling flow of ideas and results for the Shell Model are described in a manner that makes clear why this magnificent edifice has had such great resilience. Many of the ideas of the Shell Model are very elegant. They converge on a picture of nuclear states that is so all-encompassing that there has been very little room, so far, for the intrusion of subnucleon physics. Talmi takes us right up to the most recent decade in which very large computers have been able to verify and expand upon earlier views of the effective interaction by directly diagonalizing the matrices pertaining to the myriad of nuclear states that arise from several valence nucleons beyond closed shells. This review is then a celebration of a most successful model of atomic nuclei and of its underlying ideas. xi PREFACEThe second article of this volume is also massive and pertains to a subject that has become very important for the field. Chiral Perturbation Theory has been one of the few quantitative tools for coping with the theory of the strong interactions, QCD, which is both remarkably simple to express as a fundamental Lagrangian and notoriously ...

Centroids of the effective nucleon-nucleon interaction for the mass region A =28-64 are extracted directly from experimental single-particle spectra, by comparing single-particle energies relative to different cores. Uncertainties in the centroids are estimated at approximately 100 kev, except in cases of exceptional fragmentation of the single-particle strength. The use of a large number of inert cores allows the dependence of the interaction on mass or model space to be investigated. The method permits accurate empirical modifications to be made to realistic interactions calculated from bare nucleon-nucleon potentials, which are known to possess defective centroids in many cases. In addition, the centroids can be used as input to the more sophisticated fitting procedures that are employed to produce matrix elements of the effective interaction.
