The ratios of inclusive electron scattering cross sections of [Formula Presented] [Formula Presented] and [Formula Presented] to [Formula Presented] have been measured for the first time. It is shown that these ratios are independent of [Formula Presented] at [Formula Presented] for [Formula Presented] where the inclusive cross section depends primarily on the high momentum components of the nuclear wave function. The observed scaling shows that the momentum distributions at high-momenta have the same shape for all nuclei and differ only by a scale factor. The observed onset of the scaling at [Formula Presented] and [Formula Presented] is consistent with the kinematical expectation that two-nucleon short range correlations (SRC) dominate the nuclear wave function at [Formula Presented] The values of these ratios in the scaling region can be related to the relative probabilities of SRC in nuclei with [Formula Presented] Our data, combined with calculations and other measurements of the [Formula Presented] ratio, demonstrate that for nuclei with [Formula Presented] these probabilities are 4.9–5.9 times larger than in deuterium, while for [Formula Presented] it is larger by a factor of about 3.8. © 2003 The American Physical Society.
