Multifaceted Decay of ^{116}Cs.

The multifaceted decay properties of ^{116}Cs near the proton drip line have been studied at ISOLDE, CERN. More than six new unbound states of ^{116}Xe have been identified. A novel phenomenon of low energy isoscalar octupole resonance has been observed. After proton decay, that state populates both 11/2^{+} and 11/2^{-} states of ^{115}I. First observation of delayed two protons is reported in the medium heavy region and this exotic decay mode is 3 orders of magnitude lower than the delayed single proton events. The fingerprint of long-range proton-proton correlation has been evidenced in the relative momentum of two protons. An indication of rare event, heavy cluster emission (^{12}C) in medium heavy nucleus is reported.
