[en] Studies are reported on the effect of translational energy on the chemical mechanisms for collisional deactivation of electronically excited recoil 13N(2D) atoms by Cl2. These studies were carried out in gas baths of 99.9, 99.0 and 90.0 mol percent of neon relative to the combined concentrations of the Cl2 quenching gas, and an additional probe reagent. N2 and NO were selected as probe reagents for their ability to remove the 13N-atoms as the 13NN product state-selectively and nonselectively, respectively. The behavior of recoil 13N(2D) atoms with Cl2 was indirectly monitored through the dependence of the 13NN yield on halogen quencher concentration. In turn, the effect of translational energy on this behavior was revealed by comparing the dependence of this yield on Cl2 between different bath gas concentrations. The observed results showed that thermalized 13N(2D) atoms behaved predictably with Cl2 in that 13NCl(X3Σ-) was formed. In the absence of secondary reactions, as was the case when Cl2 + N2 mixtures were used, the halonitrene radical dissociated to the ground-state atoms. However, its quantitative conversion to 13NNO could be seen in the presence of trace concentrations of NO. At higher translational energies, the transient halonitrene concentration was greatly reduced. This change was not attributed to its increased reactivity towards Cl2, but rather to a change in the primary reaction involving 13N(2D) and Cl2 which yielded an intermediate other than the halonitrene.

[en] Measurements of the total reaction cross section for proton drip line nucleus 12N at about 50.4 MeV/u on Si target were performed on RIBLL. Compared with its neighbor 13N, large enhancement of total reaction cross section σr for 12N is observed. This might be caused by nuclear deformation and nucleon pair effect, and the experimental inaccuracy should not be neglected. The σr of 12N calculated by using a microscopic Glauber model is in agreement with the experimental results
