摘要
The experiment was carried out at the Sector-Focusing Cyclotron in IMP. 133Sm was produced via fusion, evaporation in the reaction 40Ca(96Ru,2pn).Itsβ-delayed proton decay was studied by means of 'p-γ' coincidence in combination with a He-jet tape transport system, including half-lives, proton energy spectra (Fig. 1),γ-transitions following the proton emissions, and the branching ratios to the low-lying states in the grand-daughter nuclei. The possible spins and parities of 133Sm were extracted by fitting the experi-
The experiment was carried out at the Sector-Focusing Cyclotron in IMP. 133Sm was produced via fusion, evaporation in the reaction 40Ca（96Ru,2pn）.Itsβ-delayed proton decay was studied by means of ＂p-γ＂ coincidence in combination with a He-jet tape transport system, including half-lives, proton energy spectra （Fig. 1）,γ-transitions following the proton emissions, and the branching ratios to the low-lying states in the grand-daughter nuclei.
