Chirality and Wobbling in Atomic Nuclei
The book provides an introduction to both theoretical and experimental results on chirality and wobbling in atomic nuclei. It details the achievements in the study of chirality over the past 25 years since the first prediction of this mode of collective motion in nuclei, as well as those on the wobbling motion. It offers a detailed review of the most relevant theoretical developments on both types of collective motion and the experimental results supporting or not the theoretical predictions. Different views on wobbling are included and confronted with the contradicting experimental results on low-spin wobbling. It is intended to foster further the research on these types of exotic collective motion in nuclei. Which and how these exotic collective motions occur in nuclei, which are their predicted fingerprints and how they are supported by the experimental facts will be presented. Polemics, debates, and ambiguities of the interpretation of the experimental results will be exposed. The reader will have the opportunity to have together different views on the two phenomena which animated the scientific activity in low-energy nuclear physics in many laboratories around the world. The book will be a valuable reference for PhD students, post-docs and researchers in addition to universities and research institutions. Key Features: The first book on chirality and wobbling in nuclei Contains a comprehensive review of topics related to chirality and wobbling, including both theoretical and experimental aspects Contains chapters from leading researchers in the field.
Wobbling Motion in Nuclei: Transverse, Longitudinal, and Chiral

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.
