四核子破裂阈值以上的氘-氘散射

Deuteron-deuteron scattering above four-nucleon breakup threshold

A. Deltuva, A. C. Fonseca

摘要:

通过求解跃迁算符的精确四粒子方程,描述了在四核子破裂阈值以上能区的氘-氘弹性散射和转移反应。几个现实的核相互作用模型,包括一个有效的多核子力产生的显式$Δ$ -同量异位素激发,质子之间的库仑力也被考虑在内。微分截面,氘分析功率,出射核子极化,氘到中子的极化传递系数计算在10 MeV的氘能量。与实验数据吻合较好,说明了破碎通道的重要性。

英文摘要:

Deuteron-deuteron elastic scattering and transfer reactions in the energy regime above four-nucleon breakup threshold are described by solving exact four-particle equations for transition operators. Several realistic nuclear interaction models are used, including the one with effective many-nucleon forces generated by the explicit $Δ$-isobar excitation; the Coulomb force between protons is taken into account as well. Differential cross sections, deuteron analyzing powers, outgoing nucleon polarization, and deuteron-to-neutron polarization transfer coefficients are calculated at 10 MeV deuteron energy. Overall good agreement with the experimental data is found. The importance of breakup channels is demonstrated.
