The partial widths of the 16.1 MeV 2+ resonance in 12C

“…Here they confirmed the prior cross section measurements [1,4,8,9,14,19,20] yielding a combined result of σ pγ0 = 5.1(5) µb and σ pγ1 = 139(12) µb. Thus we consider the values for these cross sections to be reliable.…”

“…The the ratio of the two α channels from the present measurement is 19 (3), which is consistent with both previous measurements. Combining all three measurements yields σ pα,1 σ pα,0 = 19.9 (14).…”

“…The the ratio of the two α channels from the present measurement is 19 (3), which is consistent with both previous measurements. Combining all three measurements yields σ pα,1 σ pα,0 = 19.9 (14). ( 16) 1 The short-comings of their model at the 16.1 MeV resonance is due to them neglecting interference terms by summing incoherently over different α permutations.…”

“…Situated just above the proton threshold the 16.1 MeV 2 + state in 12 C has been the subject of numerous studies [1,2,3,4,5,6,7,8,9,10,11,12,13,14] with the most recent compilation published in ref. [15] and a detailed review of the decay properties of the 16.1 MeV state given in ref.…”
