We developed a method to track changes in nuclear structure from vibrational to rotational motion with increasing spin. Applying this to nuclei around mass 110 reveals a distinct transition point.
Area of Science:
- Nuclear Physics
- Atomic and Molecular Physics
Background:
- Understanding nuclear structure evolution is key to nuclear physics.
- The transition from vibrational to rotational motion in nuclei is a fundamental phenomenon.
Purpose of the Study:
- To present a straightforward method for identifying the evolution of nuclear structure.
- To analyze the transition from vibrational to rotational motion as a function of nuclear spin.
Main Methods:
- A novel prescription is introduced to analyze nuclear structure.
- The method is applied to yrast cascades in the A ≈ 110 mass region.
Main Results:
- The study successfully identifies the transition from vibrational to rotational behavior.
- A clear transition point is observed in the analyzed nuclear systems.
Conclusions:
- The proposed method effectively discerns the evolution of nuclear structure.
- The findings confirm a distinct shift from vibrational to rotational motion in nuclei around A ≈ 110.
