Query: Measurement of 2- and 3-Nucleon Short Range Correlation Probabilities in
  Nuclei   The ratios of inclusive electron scattering cross sections of He4, C12 and
Fe56 to He3 have been measured at 1 < x_B < 3. At Q^2 > 1.4 GeV^2, the ratios
exhibit two separate plateaus, at 1.5 < x_B < 2 and at x_B > 2.25. This pattern
is predicted by models that include 2- and 3-nucleon short-range correlations
(SRC). Relative to A=3, the per-nucleon probabilities of 3-nucleon SRC are 2.3,
3.2, and 4.6 times larger for A=4, 12 and 56. This is the first measurement of
3-nucleon SRC probabilities in nuclei. \\
