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...
The multinucleon transfer (MNT) reaction approach was successfully employed for the first time to measure isomeric ratios (IRs) of 211Po isomer (25/2+) and its ground state (9/2+) at IGISOL facility using a 945 MeV 136Xe beam impinged on 209Bi natPb targets. dominant production isomers compared corresponding states consistently revealed in α-decay spectra. Deduced IR populated through 136Xe+natPb found have an enhancement ≈1.8-times than that observed 136Xe+209Bi. State-of-the-art...
We calculate the free energy of finite droplets quark-gluon plasma, and hadronic bubbles in bulk near confinement phase transition. sum over quark gluon levels presence MIT bag boundary conditions. find that curvature term energy, proportional to radius droplet or bubble, is far more important than contribution surface tension, squared. This affects critical for nucleation plasma superheated hadron gas, seems lead instability (even when not supercooled) against gas bubbles.
