dc.description.abstract	Using the fusion-evaporation reaction 96Ru(58Ni,p4n)149Lu and the MARA vacuum-mode recoil separator, a new proton-emitting isotope 149Lu has been identified. The measured decay Q value of 1920(20) keV is the highest measured for a ground-state proton decay, and it naturally leads to the shortest directly measured half-life of 450+170−100 ns for a ground-state proton emitter. The decay rate is consistent with lp=5 emission, suggesting a dominant πh11/2 component for the wave function of the proton-emitting state. Through nonadiabatic quasiparticle calculations it was concluded that 149Lu is the most oblate deformed proton emitter observed to date.	en

The quantum tunneling and emission of a single constituent nucleon provide a beautifully simple and unique window into the complex properties of atomic nuclei at the extreme edge of nuclear existence. In particular, for ...
Test of JYUTube as a veto detector at MARA for background suppression in nuclear spectroscopy beyond the proton drip line

Sottili, Leandro (2018)

At JYFL-ACCLAB a Mass Analysing Recoil Apparatus (MARA) was built to per- form nuclear spectroscopy of exotic nuclei with N=Z in the region A∼80 created via fusion evaporation reactions at low energies (3-6 MeV/u). Fusion ...

Pohjoisaho, Esko (2012)

In this Master's Thesis an analysis of proton proton data measured by the ALICE (A Large Ion Collider Experiment) Collaboration at center-of-mass energies 7 TeV and 2.76 TeV is presented. The ALICE detector is located at ...

The observation of a weak proton-emission branch in the decay of the 3174-keV 53mCo isomeric state marked the discovery of proton radioactivity in atomic nuclei in 1970. Here we show, based on the partial half-lives and ...
