| simple model which allows explicit calculations of the nuclear structure function in terms of the nucleon structure function for the deuteron as well as heavier nuclei is proposed. The impulse approximation in the DIS which leads to the convolution form of the nuclear structure function is examined and forms the basis of the model. The nucleus is viewed as a bound state of nucleons in constant motion with virtual mass less than the mass of a free nucleon. The EMC effect is discussed in the context of the model. Quantitative agreement with the nuclear DIS data is obtained. It was found that most of the nucleus momentum fraction is carried by the nucleons while a small portion is carried by other constituents presumed to be responsible for binding. The momentum fraction of these binding constituents showed "saturation" behavior similar to that found for the Fermi momentum as the atomic mass number of the nucleus increases, thereby suggesting a relationship between the two. Comparison is made between the model and other possible EMC effect interpretations. Lastly, a decisive test for the convolution form in general and the nuclear virtual mass, in particular, is provided. As predicted by the model, the ratio of nuclear to nucleon... |
