Researchers investigated excited states in 102Rh using nuclear reactions and gamma-ray spectroscopy. Measurements of excited state lifetimes in 102Rh do not support the presence of static chirality, despite finding a new chiral candidate band.
Area of Science:
- Nuclear Physics
- Atomic Physics
- Spectroscopy
Background:
- Excited states in atomic nuclei are fundamental to understanding nuclear structure.
- Chirality in atomic nuclei is a complex phenomenon with implications for nuclear models.
- Previous studies have explored nuclear chirality in various mass regions.
Purpose of the Study:
- To investigate excited states in 102Rh populated via the Zr94(11B,3n)102Rh reaction.
- To characterize gamma-ray transitions and measure lifetimes in 102Rh.
- To test theoretical predictions regarding static chirality in 102Rh.
Main Methods:
- Utilized the Indian National Gamma Array spectrometer for gamma-ray detection.
- Employed angular correlation and Doppler-shift attenuation techniques for lifetime measurements.
- Compared experimental data with the two quasiparticles plus triaxial rotor model.
Main Results:
- Observed excited states in 102Rh following a fusion-evaporation reaction.
- Identified a new chiral candidate sister band.
- Measured excited state lifetimes in 102Rh for the first time in the A~100 mass region.
- Derived reduced transition probabilities.
Conclusions:
- Experimental results and theoretical calculations do not support the presence of static chirality in 102Rh.
- The findings provide crucial data for refining nuclear structure models.
- This study contributes to the understanding of nuclear phenomena in the A~100 mass region.
