“…All the proposed levels are well established by coincidence and energy sum relationships. The strongest γ ray observed is at 211 keV and corresponds to the deexcitation of the first excited state [11]. The 431-, 677-, and 889-keV γ rays were also observed by Dufour et al but were not placed in a level scheme [5].…”

“…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.…”

“…In addition, we observed 219.0 and 563.3 keV transitions. The 219.0 keV transition was reported in the previous studies [45][46][47]55,56]. However, as its placement in the level scheme has been controversial, the transition has been listed in Table II but it was not placed in the level scheme in Fig.…”

“…The γ -ray transitions are listed in Table II. Previous information on 40 Cl was obtained from β-decay [54] and heavy ion fusion studies [55,56]. The same nucleus was also populated in the "thick" -target γ -γ coincidence measurements [46,47].…”
