8. Isospin symmetry at 100Sn

Magdalena Gorska (GSI)

27/3/25 14:00

The N=Z=50 nucleus, 100Sn, is the heaviest self-conjugate and doubly magic nucleus that remains stable against particle emission, making it an exceptional candidate for shell-model studies aimed at deepening our understanding of the nuclear force.
Its structure is dominated by the strong proton-neutron interaction within the 0g9/2 orbital, leading to unique features such as spin gaps,...

23. Decay study of 95Cd and 86Tc

Xiaoyu Liu (RIKEN/HKU)

27/3/25 14:15

The structure of 95Ag and shell model calculations suggest that gamma-decaying isomers may exist in 95Cd. With the new HPGe array, decay studies can be used to investigate the structure of 95Cd, which will allow for a comparison with 95Ag to explore isospin symmetry. In the N=Z odd-odd nucleus 86Tc, there is a possibility that a T=0 5⁺ isomer exists. If the state is above the proton separation...

27. Towards $^{100}$Sn along the N=Z line

Alejandro Algora (IFIC (CSIC-Univ. Valencia))

27/3/25 14:30

$^{100}$Sn is the last double magic N=Z nucleus that remains stable considering particle emission. Studying its beta decay is challenging and interesting [1-3], since it is very difficult to produce and the beta decay of $^{100}$Sn shows the lowest estimated Logft or the largest B(GT) (superallowed Gamow-Teller (GT) transition) in the entire nuclide chart. This decay also holds the key for a...

28. Decay spectroscopy of the most neutron-deficient nuclei close to 100Sn

Joochun (Jason) Park (Center for Exotic Nuclear Studies, IBS)

27/3/25 14:45

The discovery of the most neutron-deficient nuclei in the $^{100}$Sn region has opened possibilities for new and more precise spectroscopy experiments, especially in light of the increased primary beam intensity of $^{124}$Xe at RIKEN RIBF and a combined array of HPGe detectors for high $\gamma$-ray efficiency. The three major topics are presented below.

Shell model calculations showed a...
