12. Recent mass measurements for nuclear structure and astrophysics at JYFLTRAP

Dr Anu Kankainen (University of Jyväskylä)

23/05/2018, 09:00

Oral presentation

JYFLTRAP is a cylindrical double Penning trap mass spectrometer [1] located at the Ion Guide Isotope Separator On-Line (IGISOL) [2] facility in Jyväskylä. In total, over 330 atomic masses for nuclear structure, fundamental physics and nuclear astrophysics have been measured with JYFLTRAP. In this contribution, I will discuss our recent results for nuclear structure and astrophysics.

14. Mass measurements in the vicinity of $^{78}$Ni at JYFLTRAP

Oral presentation

The double Penning-trap mass spectrometer JYFLTRAP [1] at IGISOL [2] has been recently used to measure the masses of neutron-rich Fe, Co, Ni, Cu, and Zn isotopes. The masses of these nuclei close to the Z=28 and N=50 closed shells are relevant for understanding the nuclear structure far from stability but also for the studies of core-collapse supernovae. Electron captures play a key role...

18. DISCOVERY OF THE NEW ISOTOPES $^{169}$Au, $^{170}$Hg AND $^{165}$Pt AND A NEW ISOMER OF $^{165}$Ir USING THE MARA MASS SEPARATOR IN ITS FIRST TRAILBLAZING EXPERIMENT

Joshua Hilton (University of Jyväskylä)

Oral presentation

Measurements of proton decay from nuclei near or beyond the proton dripline have been widely used in recent works to shed light on otherwise inaccessible nuclear structure information, such as mother and daughter state spin assignments. There is a high sensitivity relationship between the proton decay energy (Q$_P$) and the partial proton decay half-life, and measurements of these quantities...

8. Relative yields of tin and antimony isotopes in neutron induced fission of $^{nat}$U

Andreas Solders (Uppsala University)

23/05/2018, 10:00

Oral presentation

Improved independent fission yields will enhance our understandig of the fission process. The mass and charge distribution contain valuable information on the scission configuration and the nuclear potential-energy landscape.

To this end, a Be(p,xn)-neutron converter target and a dedicated ion guide for neutron induced fission reactions has been developed for the IGISOL-4 facility at the...

25. Finite amplitude method applied to calculation of nuclear photo absorption cross section and rotational moment of inertia

Dr Markus Kortelainen (University of Jyväskylä)

23/05/2018, 10:20

Oral presentation

The response of the atomic nucleus to external stimulation provides crucial information about its structure and the complex forces acting between constituent nucleons. To access these excited modes, within the framework of superfluid nuclear density functional theory, linear response theory, that is, the quasiparticle random-phase-approximation, (QRPA) is one of the commonly used method....
