Study of Excited States inN15andN16

Lowest(sd)2states in odd-Alight nuclei

“…The two lowest 1+ states in l6N are at excitation energies of 3.35 and 4.32 MeV [7]. Experiments [26,27] indicate that they are approximately equal combinations of 14N x (sd)1 2 3 4 5 6 7 8 * 1 0 m and l4C x (,vd)20 where the double subscripts denote JT, where T is the isospin. Thus, I have averaged the two energies to compare with the present calculation.…”

“…Some caution is necessary here, however, because of the complete dissimilarity between the decay schemes for the 8.31-MeV level in N 15 , with a 79% groundstate branch (Table II), and its apparent analog at 7.55 MeV in O 15 , which decays predominately (57%) to the f-level at 6.18 MeV with only a 3% branch to the ground state. 9 It has been suggested 9 that a small change in the wave function, due to Coulomb effects and the proximity of the N 14 importance. However, in N 15 the levels for which comparison was made between theoretical and experimental branching ratios are well below the C u -\-p threshold at 10.21 MeV so that all particles are tightly bound in the potential well, and the good agreement of the experimental results with theory is therefore considered significant.…”
