33. Intermediate-energy Coulomb excitation of 72Ni

Victor Modamio (University of Oslo)

23/05/2018, 14:00

Oral presentation

Transition strengths in the Ni isotopes between N=40 and N=50 have been recently subject of
extensive experimental and theoretical investigations [1-6], aiming to understand whether the
tensor force acts to reduce the Z=28 shell closure as the neutron g 9/2 orbit is filled towards 78 Ni.
The effect of the Z=28 shell gap quenching and its evolution from 68 Ni towards 78 Ni would be
reflected as...

4. Lifetimes of nuclear states in proton-emitting nuclei from Differential Plunger measurements.

David Matthew Cullen (University of Manchester (GB))

Oral presentation

Over the last few years, a programme of research performed at the University of Jyvaskyla, Finland has established the first measurements of the nuclear state lifetimes built above proton emitting states [1-5]. Lifetimes have been deduced in several nuclei; 109I [1], 151Lu [2,3] and 113Cs [4] for the first time using a specially constructed Differential Plunger for Unbound Nuclear States...

30. The Orsay Universal Plunger System - past, present, and feature

Dr Joa Ljungvall (CSNSM)

23/05/2018, 14:40

Oral presentation

In a collabortation between Centre de Sciences Nucléaires et de
Sciences de la Matière (CSNSM) and Institut de physique nucléaire
d'orsay (IPNO) a so-called Plunger device used for Recoil Distance
Doppler Shift measurements and Time Differential Recoil-in-Vacuum
measurements for g-factor measurements has been developed.

I will present the device, in the forefront of the transition from...

22. In-beam γ-ray measurement of Pb-184

Joonas Kalervo Ojala (University of Jyvaskyla (FI))

Oral presentation

In-beam $\gamma$-ray measurement of Pb-184

Joonas Ojala
University of Jyväskylä
joonas.k.ojala@jyu.fi

The excited states in Pb-184 were first observed at Accelerator Laboratory of the University of Jyväskylä in in-beam gamma-ray experiment using the recoil-decay tagging technique by Cocks et al. [1]. They assigned transitions belonging to a...

20. Super-FRS contributions from Finland

Dr Tuomas Grahn

23/05/2018, 15:20

Oral presentation

The Super-FRS separator-spectrometer to be built at FAIR will be able to unambiguously separate and identify all beams from p to U. The identification will be dome using the $\Delta E-B\rho-TOF$ method. Finland will provide detectors that will be used to provide data for beam identification in event-by-event mode. The tracking detectors will be constructed to provide the $B\rho$ information...

10. The SpecMAT active target – transfer reactions and gamma-ray spectroscopy in high-intensity magnetic fields

Oleksii Poleshchuk (KU Leuven, Institute for Nuclear and Radiation Physics)

23/05/2018, 15:40

Oral presentation

Studies of nuclear orbitals migration in exotic isotopes far from stability is a great challenge for modern nuclear physics. Commonly a few experiments are needed to get the necessary information about single-particle states which later can be used for the nuclear orbitals mapping. However, the same information can be collected by performing one experiment where identification of spins and...
