2p-2p decay of ⁸C and isospin-allowed 2p decay of the isobaric-analog state in ⁸B

NUCLEAR REACTIONS ⁹Be(⁹C, ⁸B), [⁹C beam from ⁹Be(¹⁶O, X) fragmentation], E=70 MeV/nucleon; measured Ep, Ip, ⁶Li-p-p correlated events from an excited state (IAS of ⁸C g.s.) in ⁸B by analyzing complete kinematics of 2p+⁶Li decay products; deduced 2p decay (isospin-allowed 2p decay between isobaric analog states). ⁹Be(⁹C, ⁸C), [⁹C beam from ⁹Be(¹⁶O, X) fragmentation], E=70 MeV/nucleon; measured Ep, Ip, ⁶Be-p-p and α-p-p-p-p correlated events from ⁸C g.s. by analyzing complete kinematics of 2p+⁶Be and α+2p+2p events.

RADIOACTIVITY ⁸C(2p); measured Ep, Ip, Eα, Iα, α-p-p-p-p coin, α-p-p coin from the decay of ⁸C g.s.
