The problem of experimental confirmation deformed shapes superheavy nuclei situated in the neighborhood ${}^{270}\mathrm{Hs}$ is discussed. Measurement energy ${E}_{2+}$ lowest $2+$ state even-even species these considered as a method for this confirmation. calculated cranking approximation heavy and nuclei. Branching ratio ${p}_{2+}{/p}_{0+}$ between $\ensuremath{\alpha}$ decay nucleus to ground $0+$ its daughter also results indicate that measurement some by electron or spectroscopy...
We report on the first measurement of ${\ensuremath{\beta}}^{+}$ and orbital electron-capture decay rates $^{140}\mathrm{Pr}$ nuclei with simplest electron configurations: bare nuclei, hydrogenlike, heliumlike ions. The measured constant hydrogenlike $^{140}\mathrm{Pr}^{58+}$ ions is about 50% larger than that $^{140}\mathrm{Pr}^{57+}$ Moreover, one bound faster neutral $^{140}\mathrm{Pr}^{0+}$ atoms 59 electrons. To explain this peculiar observation has to take into account conservation...
Mass measurements of fission and projectile fragments, produced via $^{238}\mathrm{U}$ $^{124}\mathrm{Xe}$ primary beams, have been performed with the multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) Fragment Separator (FRS) Ion Catcher a resolving power (FWHM) up to 410 000 an uncertainty down $6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}$. The nuclides were separated in flight fragment separator FRS at 300 1000 MeV/u thermalized cryogenic stopping cell....
Mass measurements of the $^{69}$As, $^{70,71}$Se and $^{71}$Br isotopes, produced via fragmentation a $^{124}$Xe primary beam at FRS GSI, have been performed with multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) Ion Catcher an unprecedented resolving power almost 1,000,000. For $^{69}$As isotope, this is first direct measurement. A uncertainty 22 keV was achieved only 10 events. $^{70}$Se 2.6 obtained, corresponding to relative accuracy $\delta$m/m = 4.0$\times 10^{-8}$, less...
High-precision mass measurements of proton-rich isotopes in the range 60≤Z≤84 were performed using novel technique Schottky spectrometry. Projectile fragments produced by 209Bi ions at 930A MeV separated with magnetic spectrometer FRS and stored cooled experimental storage ring (ESR). A typical resolving power 350 000 a precision 100 keV achieved region A≈200. Masses members α chains linked precise Qα values but not yet connected to known masses determined. In this way it is concluded that...
Time-resolved Schottky mass spectrometry has been applied to uranium projectile fragments which yielded the value for 208Hg (Z=80, N=128) isotope. The excess of ME=-13 265(31) keV obtained, used determine proton-neutron interaction strength in 210Pb, as a double difference atomic masses. results show dramatic variation lead isotopes when crossing N=126 neutron shell closure, thus confirming empirical predictions that this is sensitive overlap wave functions last valence neutrons and protons.
The core-excited isomer in fully-ionized 133Sb has been directly studied for the first time by applying novel technique of isochronous mass spectrometry at GSI. neutron-rich nuclides high charge states were produced projectile fission 411 MeV A 238U ions, separated flight fragment separator (FRS) and stored storage ring (ESR). measured excitation energy is 4.56(10) MeV. neutral-atom half-life known to be 17 μs. This shortest-lived with techniques. extended in-flight bare ions ESR, which due...
The electron shakeoff probability of $^{6}\mathrm{Li}^{2+}$ ions resulting from the ${\ensuremath{\beta}}^{\ensuremath{-}}$ decay $^{6}\mathrm{He}^{+}$ has been measured with high precision using a specially designed recoil ion spectrometer. This is first measurement pure following nuclear $\ensuremath{\beta}$ decay, not affected by multielectron processes such as Auger cascades. In this ideal textbook case for application sudden approximation, experimental ionization was found to be...
