35 MeV/nucleon ~（112）Sn +~（58）Ni碰撞带电碎片产额奇偶错动的持续性
Persistence of odd-even staggering in charged fragment yields from the 112Sn+58Ni collision at 35 MeV/nucleon
摘要：
本文研究了35 MeV/核子的112 Sn +58 Ni半周边和中心碰撞产生的碎片的电荷分布的奇偶交错效应。对于Z<16的碎片，观察到偶数电荷的明显过量产生，其对于较重的碎片减少。在外围碰撞中，交错效应持续到Z约40。对于轻碎片，交错似乎是基本上独立的碰撞的中心性，这表明它主要是有关的最后几个步骤，在热核衰变。
英文摘要：
Odd-even staggering effects on charge distributions are investigated for fragments produced in semiperipheral and central collisions of 112Sn+58Ni at 35 MeV/nucleon. For fragments with Z<16 one observes a clear overproduction of even charges, which decreases for heavier fragments. In peripheral collisions staggering effects persist up to Z about 40. For light fragments, staggering appears to be substantially independent of the centrality of the collisions, suggesting that it is mainly related to the last few steps in the decay of hot nuclei.
