β-delayed proton decays and spin assignments for 133Sm and 149Yb
The proton-rich isotope 133Sm was produced via the fusion evaporation reaction 40Ca + 96Ru. Its β-delayed proton decay was studied by p-γ coincidence in combination with a He-jet tape transport system, and half-l...

A new measurement of 208Tl levels
A new determination for the levels of the nucleus 208Tl was performed by measuring the γ-rays following the β--decay of 208Hg. Twenty-six γ-rays were assigned and three new levels of 208Tl at 1.728 MeV, 1.652 MeV...

(EC + β+) decays of the 11/2- isomer and 1/2+ ground state of 143Dy
The 1/2+ ground state and a 11/2- isomer of very neutron-deficient isotope 143Dy were produced by irradiation of an enriched target of 106Cd with 40Ca and studied by using a helium-jet fast tape-transport system ...

Half-lives of the Tz=1/2 series nuclei, 81Zr and 85Mo
The nuclei 81Zr and 85Mo with Tz=1/2 have been reinvestigated via their β-delayed proton emissions with p-γ coincidence measurement. The half-life of 81Zr has been measured to be 5.3±0.5 s, which agrees with one ...
