Research in photo-nuclear and in fundamental particle physics will be carried out at the Bates and Saskatchewan cw electron facilities, at the CERN low energy anti-proton accumulator ring, and at the BNL AGS facility. Photonuclear reactions will concentrate on the role of the nucleon delta resonance in intermediate energy reactions. The particle physics experiments will focus on two areas: (1) sub-ppm measurement of the muon anomalous magnetic moment at the AGS as a test of the renormalizability of electro-weak theory, with interest in the effects of virtual production of very high mass scale particles including the W and Z bosons; and (2), measurement of CP violating decay modes of kaons produced at CERN in proton-antiproton annihilations, with interest in, among other phenomena, observation of direct CP violating amplitudes in two-pion decay of the neutral kaon, and measurement of, or limits on, CP violation in the three-pion decay channel.

将在Bates和Saskatchewan CW电子设施、CERN低能反质子蓄积环和BNL AGS设施进行光核和基本粒子物理研究。光核反应将集中在核子增量共振在中能反应中的作用。粒子物理实验将集中在两个方面：(1)测量AGS上的Muon反常磁矩，以检验电弱理论的重整化能力，并对包括W玻色子和Z玻色子在内的极高质量尺度粒子的虚产生效应感兴趣；以及(2)在质子-反质子湮没中测量CERN产生的介子的CP破坏衰变模式，特别是观察到中性介子在两个介子衰变中的直接CP破坏幅度，以及测量或限制三介子衰变通道中的CP破坏。
