18. Recent experimental results from the JYFL-ACCLAB along the proton dripline

Kalle Auranen (University of Jyväskylä)

7/23/24, 9:00 AM

Since the previous edition of the Nuclear Structure conference in 2022, the experimental results of the Nuclear Structure Group of University of Jyväskylä, Finland, have focused in the proton dripline nuclei through in-beam recoil-decay tagging (RDT), and decay-spectroscopy techniques employing both major research installations hosted by the group, namely the vacuum-mode recoil separator MARA...

19. Shape coexistence in Sn isotopes around A=110

Giacomo Corbari (University of Milano)

7/23/24, 9:25 AM

A survey of decay properties of excited 0+ states in regions of the nuclear chart well known for shape coexistence phenomena was performed. It was focused on even-even nuclei around the Z=20 (Ca), 28 (Ni), 50 (Sn), 82 (Pb) proton shell closures and along the Z=36 (Kr), Z=38 (Sr) and Z=40 (Zr) isotopic chains [1]. The aim is to identify examples of extreme shape coexistence, namely, coexisting...

20. Electromagnetic properties of the Te isotopes: the path to collectivity and the nature of pre-collective nuclei

Ben Coombes (The Australian National University)

7/23/24, 9:45 AM

The tellurium isotopes with 52 protons show a transition from vibrator-like structures near midshell (118Te) to seniority structures near N = 82 (134Te). We report measurements of excited-state g factors and E2-transition strengths following Coulomb excitation, as well as lifetimes from Doppler-broadened line shapes, for the stable isotopes from 124Te to 130Te. These measurements, performed at...

21. Triaxiality and shape evolution in even-even Ge isotopes

Nirupama Sensharma (Argonne National Laboratory)

7/23/24, 10:05 AM

The electromagnetic properties of low-lying states in 70,72,74,76Ge isotopes have been in- vestigated using a series of high-precision multi-step Coulomb excitation measurements carried out at the ATLAS facility of the Argonne National Laboratory. The experimental setup consisted of the GRETINA multidetector array coupled to the charge heavy-ion counter, CHICO2, facilitating precise Doppler...
