Study of theNe21(t, p)Ne23reaction

Investigation of the ${}_{}{}^{21}{}_{}{}^{}\mathrm{Ne}(t, p){}_{}{}^{23}{}_{}{}^{}\mathrm{Ne}$ reaction with 3 and 3.25 MeV projectiles reveals eight new (energy) levels between $E_x=5.3\mathrm{} \mathrm{and} 6.5$ MeV. Absolute differential cross sections for 18 proton groups are reported. Distorted-wave Born approximation analysis and Hauser-Feshbach calculations indicate that $L=0\mathrm{}$ is involved in the formation of one of the members of the doublets at $E_x=3.432-3.458\mathrm{} \mathrm{and} 4.995-5.036$ MeV as well as in the formation of a new level at 5.74 ± 0.04 MeV. A mixture of $L=0\mathrm{}$ and $L=2\mathrm{}$ transfer is associated with the formation of the 1.822 MeV level. For these four levels $J^{\pi }={\frac{3}{2}}^{+}$ is deduced.
