Abstract
We use the mason cloud model of the nucleon to calculate distribution funct ions for ((d) over bar - (u) over bar) and (d) over bar/(u) over bar in the proton. Including the effect of the omega meson cloud, with a coupling con stant g(omega)(2)/4 pi approximate to 8, allows a reasonably good descripti on of the data.
