摘要:Abstract(#br)A low-energy branch is under development for the MARA vacuum-mode recoil separator at the Accelerator Laboratory of the University of Jyväskylä. This development will allow for the study of proton-rich nuclei through laser ionisation spectroscopy and mass measur...

摘要:Abstract(#br)A Triple-foil differential Plunger for Exotic Nuclei (TPEN) has been developed to measure the lifetimes of excited states in nuclei with small production cross-sections. TPEN utilises one target foil and two degrader foils to make differential lifetime measureme...

摘要:Abstract(#br)Fast-timing measurements at the focal plane of a separator can suffer from poor timing resolution. This is due to the variations in time-of-flight (ToF) for photons travelling to a given detector, which arise from the changes in the implantation positions of the...

摘要:Abstract(#br)The new neutron-deficient nuclei 240 Es and 236 Bk were synthesised at the gas-filled recoil separator RITU. They were identified by their radioactive decay chains starting from 240 Es produced in the fusion–evaporation reaction 209 Bi( 34 S,3n) 240 Es. Half-liv...

摘要:Abstract(#br)This letter reports lifetime measurements of excited states in the odd- N nucleus 163 W using the recoil-distance Doppler shift method to probe the core polarising effect of the i 13 / 2 neutron orbital on the underlying soft triaxial even-even core. The ratio B...

摘要:Abstract(#br)MARA is a new recoil mass separator in the Accelerator Laboratory of University of Jyväskylä (JYFL-ACCLAB) with a mass resolving power of 250 and an ion-optical configuration of QQQD E D M . In this paper the construction, control and conditioning of its electro...

摘要:Abstract(#br)A non-reference based method to determine internal conversion coefficients using the SAGE spectrometer is carried out for transitions in the nuclei of 154 Sm, 152 Sm and 166 Yb. The Normalised-Peak-to-Gamma method is in general an efficient tool to extract internal c...

摘要:Summary(#br)Our aim was to evaluate the impact of deep wound infection after hip fracture surgery on functional outcome and mortality. Two thousand, two hundred and seventy-six consecutive surgically treated patients with non-pathological fractures, aged over 50 years (mean age 7...
