“…Excited states in 40 Cl were first identified in ( 7 Li, 7 Be) and ( 11 Be, 11 C) chargeexchange reactions on 40 Ar [9]. Two additional experiments using the 9 Be( 36 S,αp) 40 Cl reaction [10,11] have resulted in identification of states with spins from 1 to 8, most likely all being of negative parity. Of these, only a state at 211 keV could be positively associated with a γ ray observed in the β-decay experiment [5,11].…”

“…Hence, the β decay is populating a different set of lower-spin states than those populated by the heavy-ion reaction. For 43 Ar, four excited states were observed by Jelley et al using the 48 Ca(α, 9 Be) 43 Ar reaction [12], whereas Maréchal et al used inelastic proton scattering with a radioactive 43 Ar beam to identify a separate state [13]. Only the state at 1.74 ± 0.05 MeV has a possible corresponding state to those previously observed in β decay [8].…”
