In our everyday world, we have many examples of objects that rotate or vibrate. When we translate this down to the microscopic world of the nucleus, it is interesting to explore whether the nucleus can also undergo rotation and vibration, so-called collective motion, which could be inferred from the pattern and properties of excited states that a given nucleus is able to adopt.

This course text provides an intermediate level treatment on the topic of the nuclear structure, focussing on the collective properties of atomic nuclei. It follows the authors' earlier work, 'Nuclear Data: A Primer', which provided an introduction to nuclear structure. This book goes into more detail on the specific topic of collective motion in nuclei.

The book is divided into six main chapters that outline the necessary theory and critically review it in the light of available data. Video-based exercises are included to promote student learning and understanding. The book follows a pathway that is very useful to potential readers, particularly PhD students and advanced undergraduate students.
