72. In-beam gamma-ray spectroscopy of exotic nuclei at the RIBF

Kathrin Wimmer (University of Tokyo (JP))

06/12/2018, 16:30

Invited

At the Radioactive Isotope Beam Factory in-beam gamma-ray spectroscopy experiments take advantage of the wide range of radioactive ion beams produced by the projectile fragmentation and fission. Isotopes of interest are separated by the BigRIPS fragment separator and guide to a secondary reactions target. Reaction residues are identified either in the ZeroDegree spectrometer or with the...

57. Spectroscopy of muonic atoms and the proton radius puzzle

Dr Aldo Antognini (Paul Scherrer Institute)

Invited

We have measured several 2S-2P transitions in muonic hydrogen (μp), muonic deuterium (μd) and muonic helium ions (μ3He, μ4He). From muonic hydrogen we extracted a proton charge radius 20 times more precise than obtained from electron-proton scattering and hydrogen high-precision laser spectroscopy but at a variance of 7σ from these values. This discrepancy is nowadays referred to as the...

53. R3B-NeuLAND - Detection of Fast Neutrons

Konstanze Boretzky (GSI)

06/12/2018, 17:30

Invited

The high-resolution, large-acceptance neutron time-of-flight spectrometer NeuLAND is the new neutron detector being developed for
the R3B setup (Reactions with Relativistic Radioactive Beams) at
FAIR. NeuLAND is dedicated to the detection of high-energy neutrons
up to 1GeV. In this talk, I will report on the design concept and the status of construction. An overview over the experimental...

31. Evidence for clustering in $^{20}$Ne: the Morinaga nucleus

Ms Senamile Masango (University of the Western Cape (ZA))

Submitted

The reduced transition probability or $B(E2;0^+_1\rightarrow 2^+_1)$ value and the spectroscopic quadrupole moment of the first excited 2$^{+}_{1}$ state, $Q_{_S}(2^{+}_{1})$, at 1.633 MeV in $^{20}$Ne have been determined at safe energies using the {\small TIGRESS} and AFRODITE arrays at TRIUMF and iThemba LABS, respectively. Large values of $B(E2;0^+_1\rightarrow 2^+_1)=22.4(16)$ W.u. and...
