Research InterestsI study properties of unstable nuclei located far from the line of beta stability. ATLAS with its high-quality intense beams of heavy ions is an ideal tool for producing nuclei with excess of protons. Listed below are recent experimental examples related to:
- the doubly-magic 100Sn nucleus [1,5],
- nuclei spontaneously emitting protons ,
- levels above the proton threshold in light proton-rich nuclei, which are situated along the path of the astrophysical rapid proton-capture process [3,4],
- isomers in very heavy transfermium nuclei .
All these experiments were performed using the GAMMASPHERE array of gamma-ray detectors and the Argonne Fragment Mass Analyzer.
