The near-symmetric complete fusion reaction $^{78}\mathrm{Kr}+^{107}\mathrm{Ag}\ensuremath{\rightarrow}^{185}\mathrm{Bi}^{*}$ was studied at the gas-filled recoil separator SHANS with an attempt to synthesize extremely neutron-deficient proton-unbound $^{182,183}\mathrm{Bi}$ isotopes. No decay events which could be attributed them were observed. two- and three-particle evaporation residues $^{180,179}\mathrm{Hg}$ ($\ensuremath{\alpha}p, \ensuremath{\alpha}pn$) $^{183,182}\mathrm{Pb}$ ($pn,...
The new isotope $^{224}\mathrm{Np}$ was produced in the fusion-evaporation reaction of $^{40}\mathrm{Ar}+^{187}\mathrm{Re}$ and identified through evaporation residue (ER)--$\ensuremath{\alpha}$-decay correlation measurements using digital pulse processing technique. Two $\ensuremath{\alpha}$-decay branches with $\ensuremath{\alpha}$ energies 9137(20) 8868(62) keV were assigned to $^{224}\mathrm{Np}$, decaying two excited states $^{220}\mathrm{Pa}$. half-life deduced be...
The decay properties of the short-lived isotope $^{220}\mathrm{Pa}$ were re-investigated via reaction $^{40}\mathrm{Ar}+^{187}\mathrm{Re}$ at gas-filled recoil separator Spectrometer for Heavy Atoms and Nuclear Structure. digital pulse processing technique was applied to resolve evaporation residues--$\ensuremath{\alpha}$ ($\mathrm{ER}\ensuremath{-}\ensuremath{\alpha}$) pileup signals in $^{220}\mathrm{Pa}$. $\ensuremath{\alpha}$-decay chain leading well-known $^{216}\mathrm{Ac}$ established...
The $\ensuremath{\alpha}$ decay of $^{222}\mathrm{U}$ was reinvestigated using a general least-square superpulse fitting algorithm dedicated to resolving pileup signals in the very short-lived nuclei. $\ensuremath{\alpha}$-particle energy revised be 9246(8) keV, and precision improved significantly compared with previous result. Using present energy, anomaly systematics $\ensuremath{\alpha}$-decay reduced width ${\ensuremath{\delta}}^{2}$ observed at ${N}_{p}{N}_{n}$ scheme is solved, all...
We have prepared NaYF4:Er3+/Yb3+/Ca2+ phosphors using the solvothermal method and discussed influence of annealing on crystal structure, morphology, photoluminescence characteristics in this work. The results show that, with increase temperature, crystallization phase changes from a single cubic structure to mixed hexagonal phases morphology is also condensed spherical particles sheets. In particular, PL intensity annealed phosphor becomes much stronger than that unannealed phosphor. An...
