This book was released on 2017-03-20 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis established the existence of wobbling at low spin and low deformation in the Z~60, N~76 nuclear region. This opens the region to further searches for wobbling and shows that wobbling is not confined to a particular quasiparticle orbital, spin or deformation. While deformed nuclei usually have axial shape, triaxial shapes have been predicted at low to moderate spins in certain regions of the nuclear chart (e.g. Z~60, N~76 and Z~46, N~66). Observation of one of the fingerprints of triaxiality, chirality and wobbling, guarantees that the nucleus is axially asymmetric. While chirality has been observed in numerous nuclei from many regions of the nuclear chart, wobbling, prior to this work, had only been observed at high spins in super deformed bands in five nuclei confined to the Z~70, N~90 region. Additionally, this dissertation establishes a new interpretation for the wobbling phenomenon. It shows for the first time that the nucleon aligns to the short axis, which explains the decrease in wobbling energies with angular momentum seen on this and all previous wobbling nuclei while still explaining the observed B(E2out)B(E2in) ratios. This is a new phenomenon, which is in contrast to the increase of the wobbling energies predicted by Bohr and Mottelson.

This book was released on 2022-11-22 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents significant new observations of nuclear wobbling, and thus expands our understanding of nuclear triaxiality and its prevalence in the nuclear chart. Triaxial nuclear shapes are a very rare phenomena and their experimental identification often relies on two unique signatures – nuclear wobbling motion and chiral rotation. While nuclear chirality is a well-studied phenomenon, experimental observations of wobbling nuclei are rather limited. With the identification of 135Pr and 187Au as wobblers, this work establishes triaxiality to be a general phenomenon present in different regions of the nuclear chart, irrespective of any particular spin or deformation. A major focus of this work is the detailed investigation of the different kinds of wobbling modes. Depending on the geometry of the nuclear system, wobbling can be classified into two types – longitudinal and transverse. This work has, for the first time, reported evidence of the possible coexistence of both forms of wobbling in a single nucleus. Another important result reported in this work is the very first observation of co-existing chiral and wobbling modes in the 135Pr nucleus. This thesis details the experimental methods that led to this breakthrough, along with pertinent theoretical interpretations.

Book excerpt: Nuclear Moments focuses on the processes, methodologies, reactions, and transformations of molecules and atoms, including magnetic resonance and nuclear moments. The book first offers information on nuclear moments in free atoms and molecules, including theoretical foundations of hyperfine structure, isotope shift, spectra of diatomic molecules, and vector model of molecules. The manuscript then takes a look at nuclear moments in liquids and crystals. Discussions focus on nuclear paramagnetic and magnetic resonance and nuclear quadrupole resonance. The text discusses nuclear moments and nuclear models, as well as simple conclusions from experimental data and graphical representations of nuclear models and moments. An explanation of symbols used in the manuscript is also presented. The book is a dependable reference for readers interested in the study of nuclear moments.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide a detailed introduction to the state-of-the-art covariant density functional theory, which follows the Lorentz invariance from the very beginning and is able to describe nuclear many-body quantum systems microscopically and self-consistently. Covariant density functional theory was introduced in nuclear physics in the 1970s and has since been developed and used to describe the diversity of nuclear properties and phenomena with great success.In order to provide an advanced and updated textbook of covariant density functional theory for graduate students and nuclear physics researchers, this book summarizes the enormous amount of material that has accumulated in the field of covariant density functional theory over the last few decades as well as the latest developments in this area. Moreover, the book contains enough details for readers to follow the formalism and theoretical results, and provides exhaustive references to explore the research literature.

This book was released on 2010-04-08 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: It all began with Markus Jochum approaching one of us (HvS) – “when you guys are doing interviews with senior scientists from oceanography and related sciences, why are you not doing Walter Munk?” Indeed, why not? Walter Munk, an icon in oceanography, had just given a wonderful talk in a symposium in honor of his 90th birthday, sweeping a grand circle from his earliest work with Chip Cox on airborne measurements of ocean surface roughness to the latest satellite data – not simply a review, but the struggle of an active scientist opening up new perspectives – as inspiring and stimulating as when one of us (KH) rst met him at the Ocean Waves Conference in Easton in 1961 (Fig. I. 1). Walter immediately agreed to share with us his recollections on the nearly seventy years of his path-breaking contributions in a sheer amazing range of topics, from ocean waves, internal waves, ocean currents, tides, tsunamis, sea level, microseisms and the rotation of the earth to ocean acoustic tomography. With “you guys” Markus was referring to HvS and the various partners HvS had 1 invited to join him in conducting a series of interviews of retired colleagues.
