Mass excesses of short-lived $A=2Z\ensuremath{-}1$ nuclei $^{63}\mathrm{Ge}$, $^{65}\mathrm{As}$, $^{67}\mathrm{Se}$, and $^{71}\mathrm{Kr}$ have been directly measured to be $\ensuremath{-}46\text{ }921(37)$, }937(85)$, }580(67)$, }320(141)\text{ }\text{ }\mathrm{keV}$, respectively. The deduced proton separation energy $\ensuremath{-}90(85)\text{ }\mathrm{keV}$ for $^{65}\mathrm{As}$ shows that this nucleus is only slightly unbound. X-ray burst model calculations with the new mass excess...
Isochronous mass spectrometry has been applied to neutron-deficient $^{58}\mathrm{Ni}$ projectile fragments at the HIRFL-CSR facility in Lanzhou, China. Masses of a series short-lived ${T}_{z}=\ensuremath{-}3/2$ nuclides including $^{41}\mathrm{Ti}$, $^{45}\mathrm{Cr}$, $^{49}\mathrm{Fe}$, and $^{53}\mathrm{Ni}$ have measured with precision 20--40 keV. The new data enable us test for first time isobaric multiplet equation (IMME) $fp$-shell nuclei. We observe that IMME is inconsistent...
Revolution frequency measurements of individual ions in storage rings require sophisticated timing detectors. One common approaches for such detectors is the detection secondary electrons released from a thin foil due to penetration stored ions. A new method based on analysis intensities was developed which enables determination charge each ion simultaneously with measurement its revolution frequency. Although mass-over-charge ratios 51Co27+ and 34Ar18+ are almost identical, therefore,...
This letter proposes a quantification phase gradient near-field focusing metasurface (MS) to improve the transmission coefficient of microwave wireless power transfer (WPT) system.

Isochronous mass spectrometry has been applied in the storage ring CSRe to measure masses of neutron-rich $^{52--54}\mathrm{Sc}$ and $^{54,56}\mathrm{Ti}$ nuclei. The new excess values $ME(^{52}\mathrm{Sc})=\ensuremath{-}40525(65)$ keV, $ME(^{53}\mathrm{Sc})=\ensuremath{-}38910(80)$ $ME(^{54}\mathrm{Sc})=\ensuremath{-}34485(360)$ deviate from Atomic Mass Evaluation 2012 by $2.3\ensuremath{\sigma}, 2.8\ensuremath{\sigma}$, $1.7\ensuremath{\sigma}$, respectively. These large deviations...
The projectile fragmentation reactions of ${}^{40}$Ar at 57 MeV/nucleon on ${}^{9}$Be and ${}^{181}$Ta targets have been studied by the Radioactive Ion Beam Line in Lanzhou (RIBLL) Heavy-Ion Research Facility (HIRFL). momentum distributions fragments measured competition between different mechanisms are observed. production cross sections obtained compared with empirical parametrization section (EPAX), abrasion-ablation (AA), heavy-ion phase space exploration (HIPSE) models, target...
With the commissioning of Cooler Storage Ring at Heavy Ion Research Facility in Lanzhou (HIRFL-CSR), a pilot experiment operating CSRe isochronous mode to test power HIRFL-CSR for measuring mass short-lived nucleus was performed December 2007. The transition point γ t is 1.395 which corresponds energy about 368 MeV/u ions with atomic number-to-charge ratio A/q = 2. fragments 2 36 Ar were injected into and their revolution frequencies measured fast time pick-up detector thin foil circulating...
