Experimental study of the knockout reaction mechanism usingO14at 60 MeV/nucleon

“…The time and position resolutions of the detectors from the experimental data are also included in the simulation. A few excited states of 13 O ranging from 2.7 MeV to 6.1 MeV have been reported previously [32][33][34][35][36]. All excited states of 13 O lie above its two proton separation energy (S 2p = 2.1 MeV).…”

“…All excited states of 13 O lie above its two proton separation energy (S 2p = 2.1 MeV). The one-proton decay product 12 N also has no bound excited state [33]. Due to the unfavorable penetrability, the two proton decay is at least 3 orders of magnitude less probable than one proton decay [32].…”

“…Individual measurements over the years [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] have reported conflicting results, some of which also disagree with the most recent compilations [18,19] 12 N levels (Q = -22.135 MeV) has not been reported [18,19]. In this work, we have utilized the JENSA gas jet target for a measurement of the 14 N(p,t) 12 N transfer reaction.…”

Asymptotic normalization coefficients and radiative widths

“…The radiative width of the second resonance was a controversial subject theoretically. The proton resonance width of the second resonance is 51 ± 20 keV [16]. The square of the proton ANC of the ground 12 N state measured in [15] is 1.73 ± 0.25 fm −1 .…”
