We report the first detection of the second-forbidden, non-unique,
$2^+\rightarrow 0^+$, ground-state transition in the beta decay of $^{20}$F.
A low-energy, mass-separated $^{20}$F beam produced at the IGISOL
facility in Jyväskylä, Finland, was implanted in a thin carbon foil and the
beta spectrum measured using a magnetic transporter and a plastic-scintillator
detector. The log-ft value...
Light nuclei has received new interest with the advent of ab-initio calculations.
In order to test these calculations we need detailed experimental knowledge for comparison.
A prime test candidate is 8Be as it has both a-cluster and single particle states that interfere.
The 8Be system can be populated using the 7Li(p,g)8Be reaction which has a resonance with a branching ration of ~1‰ at...
The recent measurement of the Neutron Star Merger event by LIGO [1] and subsequent optical measurements have revealed that Neutron star mergers are probably one of the primary sites for the r-process of nucleosynthesis [2]. An important source of uncertainty in the r-process models is the nuclear data input [3], especially important is the neutron capture cross-section which is directly...
The MONSTER (MOdular Neutron SpectromeTER) is a time-of-flight (TOF) spectrometer based on scintillation detectors [1,2]. It is originally intended as a research instrument for DESPEC, in the Low Energy Branch of the Super-FRS recoil separator in FAIR, to be utilized in the beta-delayed neutron emission studies far from the beta stability line. The modularity of the detector array...
One of the many open questions regarding fission is the origin of the angular momentum of the primary fission fragments. Although it is well established that they carry considerable amount of angular momentum, there are competing theories on how this is generated. It is thus desirable to obtain information on the angular momenta of the fragments as it can provide insights on the properties of...
The steady progress over the past twenty years in the development of beams of radioactive isotopes has allowed to vastly expand the objectives of experimental nuclear research. It is becoming possible to study in the laboratory a range of nuclear reactions that take place in exploding stars providing crucial information to understand how the chemical elements that we find on Earth were formed....
An significant the upgrade of the Dubna Radiactive Ion Beams facility is the replacement of the ACCULINNA fragment separator with a new high acceptance device - the ACCULINNA-2. The project of a new in-flight facility for low energy $30-60$ AMeV primary beams with $3 ≤ Z ≤ 36$ has been started in 2011. The new device is destined to add considerably to the studies of drip-line nuclei performed...
