The physics program supported by this grant is directed at thestudy of experimental nuclear physics at the HERA collider ring inGermany. Research will be carried out in high energy electronscattering to determine the contribution of quarks and gluons tothe intrinsic angular momentum of the proton and neutron bymeasuring the scattering of polarized electrons on polarizedtargets. The main emphasis will be on studying the gluonpolarization, the orbital angular momentum contribution to thenucleon spin, and transverse polarization effects in nucleons.Education and training of both, undergraduate and graduatestudents, and postdoctoral scholars, as well as outreach aimed atthe general public is an important aspect of this research program.

该基金支持的物理学项目旨在研究德国HERA对撞机环的实验核物理。将开展高能电子散射研究，通过测量极化电子在极化靶上的散射，确定夸克和胶子对质子和中子的内禀角动量的贡献。重点是研究胶子极化、轨道角动量对核子自旋的贡献以及核子中的横向极化效应。本科生和研究生以及博士后学者的教育和培训以及针对公众的推广是该研究计划的一个重要方面。
