Study of exotic decay of Cs isotope close to the proton drip line

The neutron-deficient $^{115}$Cs 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 γ-detector array (four Clovers) at the ISOLDE decay station (IDS). In this re...

Descripción
Sumario:The neutron-deficient $^{115}$Cs 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 γ-detector array (four Clovers) at the ISOLDE decay station (IDS). In this report, results on observed $\beta$-delayed particle emission from $^{115}$Cs, 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 $^{115}$Cs was extracted. The obtained half-life is in agreement with previous reported value. For the first time, the p-unbound states of $^{115}$Xe, obtained by measuring beta-delayed protons from $^{115}$Cs is reported.
