Dostęp zamkniętyβ-delayed proton emission from <sup>26</sup>P and <sup>27</sup>S
| dc.abstract.en | Delayed emission of protons following β decay of neutron deficient nuclei 26P and 27S was investigated at the ACCULINNA separator in the Flerov Laboratory of Nuclear Reactions at Dubna. Ions of interest, identified in flight, were implanted into the active volume of the gaseous optical time projection chamber, which allowed us to record tracks of charged particles emitted in the decay. Total branching ratios for β-delayed proton emission and for β-delayed two-proton emission were determined. In addition, energy spectra for delayed protons below 2 MeV were established. Our findings for 26P agree with results of previous experiments. In the case of 27S, however, the observed probability of delayed proton emission is an order of magnitude larger than reported in literature. Two new strong proton transitions were identified representing decays of the first two excited states of 27P to the ground state of 26Si. The probability ratio of γ-to-proton emission from these states is discussed. |
