22. Spectroscopy of rare isotopes with the Active Target Time Projection Chamber

Daniel Bazin (Facility for Rare Isotope Beams)

7/23/24, 10:55 AM

The Active Target Time Projection Chamber (AT-TPC) has been used in experiments aimed at the exploration of structural effects in radioactive nuclei using one step reactions such as transfer or elastic and inelastic scattering. When used as a solenoidal spectrometer by placing it inside a magnetic field, the AT-TPC allows to perform this type of measurement in inverse kinematics with much...

23. Nuclear structure studies using cold antiprotons at AEGIS

Fredrik Gustafsson (CERN)

7/23/24, 11:20 AM

At CERN's antimatter factory, antiprotons are routinely produced and cooled in bunches utilizing the ELENA/AD decelerators. The low energy antiprotons are distributed to a wide range of trapping experiments primarily aiming at precision tests of fundamental symmetries and interactions [1]. The Antimatter Experiment: Gravity, Interferometry, Spectroscopy (AEGIS) at the antimatter factory has...

24. Complete decay spectroscopy of neutron-rich Cl isotopes with FDSi

Ian Cox (University of Tennessee, Knoxville)

7/23/24, 11:40 AM

Nucleon-nucleon correlaRons lead to changes in shell structure, such as the islands of inversion. The N=28 shell gap has been frequently probed in nuclei south of 48Ca, finding that intruder configuraRons, which correspond to neutron excitaRons across the gap, play an important role in those neutron-rich isotopes at low energy. The locaRon of the states is related to the neutron shell...

25. First Identification of the 0^+_4 and 0^+_5 levels in 100Zr at ANL-ATLAS

Jin Wu (Brookhaven National Laboratory)

7/23/24, 12:00 PM

An abrupt shape change from spherical to deformed ground states has been observed between 98Zr (N = 58) and 100Zr (N = 60) [1]. Monte Carlo shell model (MCSM) cal- culations suggest that the rapid change in the relative excitation energy of spherical and prolate structures fulfills the requirements of a first-order phase transition, and predict an excitation energy of the 0+4 spherical state...
