170. Revealing microscopic origins of shape coexistence in the Ni isotopic chain

Silvia Leoni (MI)

5/17/19, 9:00 AM

Invited

Since the 80’s, various mean-field theoretical approaches indicated neutron rich Nickel isotopes among the best candidates for the appearance of the shape coexistence phenomenon, including the possibility of finding its most extreme manifestation, i.e. shape isomerism. Shape isomerism arises from the existence of a secondary deformed minimum at large deformation in the nuclear potential energy...

199. Nuclear structure physics with radioactive-ion beams at HIE-ISOLDE

L. P. Gaffney (ISOLDE, CERN, Geneva, Switzerland)

5/17/19, 9:30 AM

Invited

HIE-ISOLDE [1] at CERN reached the end of phase 2 in 2018, operating with four cryomodules for the first time and reaching the original design energy of 10 MeV/$u$ for radioactive ion beams.
Experiments have been focused on two experimental setups so far, with the Miniball HPGe array [2] taking most of the beam time and the Scattering Experiments Chamber (SEC) concentrating on reactions with...

38. First high-precision measurement of the low-lying isovector M1 strength in Li-6 at the photon point

Norbert Pietralla (TU Darmstadt)

5/17/19, 10:00 AM

Oral

Since neither of the hydrogen nor helium nuclei have a particle-bound excited state, Li-6 is the lightest nuclide in the entire nuclear chart for which an excited state decays predominantly by gamma-ray emission. The particle-decay of its 0+ state with isospin T=1 at 3563 keV excitation energy is parity-forbidden, and it decays exclusively by a strong isovector M1 transition to the 1+ ground...

135. Quest of octupole deformation in very light Te isotopes

Dr Dmitry Testov

5/17/19, 10:20 AM

Oral

Excited states of $^{31}$S and $^{31}$P mirror nuclei were recently studied using the same fusion evaporation reaction $^{24}$Mg($^{12}$C, 1$\alpha$1p) and $^{24}$Mg($^{12}$C, 1$\alpha$1n). The 45~MeV beam was delivered by the XTU-Tandem accelerator at LNL Legnaro. The detection system was composed of GALILEO $\gamma$-ray spectrometer coupled to 4$\pi$ Si ball Euclides and to Neutron Wall....
