Study of exotic decay of Cs isotope close to the proton drip line
The neutron-deficient Cs-115 was produced at ISOLDE, CERN by spallation reaction using 1.4 GeV proton on LaC2 target. The exotic decay modes were studied by using a charged particle array (DSSD and pad detectors) and a gamma-detector array (four Clovers) at the ISOLDE decay station (IDS). In this re...

| Sumario: | The neutron-deficient Cs-115 was produced at ISOLDE, CERN by spallation reaction using 1.4 GeV proton on LaC2 target. The exotic decay modes were studied by using a charged particle array (DSSD and pad detectors) and a gamma-detector array (four Clovers) at the ISOLDE decay station (IDS). In this report, results on observed beta-delayed particle emission from Cs-115, a nucleus close to proton drip line, is presented. By measuring the time distribution in the delayed proton spectrum, the half-life of the ground state of Cs-115 was extracted. The obtained half-life is in agreement with previous reported value. For the first time, the p-unbound states of Xe-115, obtained by measuring beta-delayed protons from Cs-115 is reported. |
