This thesis presents two significant results in the field of precision measurements in low-energy nuclear physics. Firstly, it presents a precise half-life determination of 11C, leading to the most precise ft-value for a beta decay transition between mirror nuclides, an important advance in the testing of the electroweak sector of the Standard Model. Secondly, it describes a high-precision mass measurement of 56Cu, a critical nucleus for determining the path of the astrophysical rapid-proton capture process, performed by the author using the LEBIT Penning trap at the National Superconducting Cyclotron Laboratory. This new measurement resolves discrepancies in previously-reported calculated mass excesses. In addition, the thesis also presents the construction and testing of a radio-frequency quadrupole cooler and buncher that will be part of the future N = 126 factory at Argonne National Laboratory aimed at producing nuclei of interest for the astrophysical rapid-neutron capture process for the first time.

This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.

The subject of this Institute is the importance of Spin and Symmetry measurements in probing the Standard Model and QCD, polarization in lepton-quark interactions, nucleon spin structure functions, spin effects in high energy hadronic interactions, and electromagnetic spin physics at medium energies.The pedagogical nature of the invited talks makes this book suitable for senior graduate students and subatomic physicists in general, while the specialist talks make the volume useful to practitioners in the field.

Excited State Lifetime Measurements attempts to assist in clarifying and unifying the many characteristics and definitions of excited state lifetime measurements. The contents of this book are derived from a series of lectures presented to a research group in the University of New Mexico in 1967. The relevance as well as the methods and measurements of data treatment of excited state lifetimes are featured in this book. The first three chapters provide a brief discussion on concepts and applications of excited state lifetime measurements. Experimental methods and systems are also introduced in these chapters. Chapter 4 delves into more complex systems (serial decay kinetics and resonance energy transfer) while Chapter 5 focuses on the method of least squares fitting, its uses, and misuses. Chapters 6 to 8 mainly discuss the convolution integral and its different applications while Chapter 9 gives a more detailed presentation of instrumentation. The last two chapters discuss special errors and approaches to new methodologies regarding the study of the excited state lifetime measurements. The book will be useful to students and scientists including analytical chemists, photochemists, photobiologists, spectroscopists, and physicists.
