The SeaQuest experiment is being carried out at Fermi National Accelerator Lab (FNAL) to investigate the nucleon structure with the Drell-Yan process. It utilizes the 120-GeV proton beam extracted from the FNAL Main Injector and targets of liquid hydrogen, liquid deuterium, carbon, iron and tungsten. The solid targets are used to measure the nuclear effects. This paper describes the flavor asymmetry of light anti-quark distributions in the proton ([Formula: see text]) and the angular distribution of Drell-Yan process. The Boer-Mulders function ([Formula: see text]) can be derived from the size ([Formula: see text]) of [Formula: see text] modulation. SeaQuest finished the second data-taking period in August 2014. Preliminary results of [Formula: see text] and [Formula: see text] are reported.

Recent investigations have shown that the inelastic scattering of electrons in gases exhibits some very interesting phenomena. In previous papas we have described the angular distribution of the scattering of electrons which have lost a discrete amount of energy. Papers I and II described preliminary results which established the existence of diffraction effects at large angles in a number of gases. In Paper III the measurements were carried out over a range of velocities lower than those previously studied, results being obtained for incident electron energies down to within a few volts of the excitation potential. angular distributions were obtained for the inelastic scattering of electrons in hydrogen, helium, and argon between the angles 10° and 155°. The present paper describes the extension of the measurements to methane, nitrogen, neon and mercury vapour.

The reaction 20 O ( d , t ) has been studied in inverse kinematics using a secondary radioactive beam produced with the SPIRAL facility at GANIL. Fragments, light charged particles and gamma rays were measured with the TIARA, MUST2, VAMOS and EXOGAM detectors and preliminary results are reported. The level scheme of 19 O is built and the spin and parity of one state is tentatively assigned using the one-neutron transfer angular distribution.
