Experimental Evidence for Transverse Wobbling in ^{105}Pd

Area of Science:

• Nuclear Physics
• Atomic Physics

Background:

• Rotational bands provide insights into nuclear structure.
• Wobbling motion is a complex nuclear phenomenon observed in specific nuclei.

Purpose of the Study:

• To identify and characterize new rotational bands in ^{105}Pd.
• To investigate the presence of transverse wobbling motion in this nucleus.
• To compare experimental findings with theoretical models.

Main Methods:

• Spectroscopic analysis of nuclear transitions.
• Identification of rotational bands based on energy levels and transition properties.
• Comparison with theoretical calculations using covariant density functional theory and particle rotor models.

Main Results:

• Discovery of new rotational bands in ^{105}Pd built on the ν(h_{11/2}) configuration.
• Observation of transverse wobbling characteristics, including ΔI=1 E2 transitions and decreasing wobbling energy with spin.
• Good agreement between experimental data and theoretical predictions.

Conclusions:

• First experimental evidence for transverse wobbling bands based on a one-neutron configuration.
• First observation of wobbling motion in the A∼100 mass region.
• Validation of theoretical models for describing nuclear wobbling.
