A. Lepineszily et al., SPECTROSCOPY OF THE UNBOUND NUCLEUS N-11 BY THE C-12(N-14, C-15)N-11 TRANSFER-REACTION, Physical review letters, 80(8), 1998, pp. 1601-1604
A spectroscopic study of the proton-rich, particle unstable nucleus N-
11 has been performed using the multinucleon transfer reaction C-12(N-
14,C-15)N-11 at 30A MeV incident energy at GANIL. Levels of N-11 are o
bserved as well defined resonances in the spectrum of the C-15 ejectil
es. They are localized at 2.18(5), 3.63(5), 4.39(5), 5.12(8), and 5.87
(15) MeV above the C-10 + p threshold. The comparison of the measured
widths with R-matrix calculations allows the estimation of spins and p
arities for these resonances.
