We have measured the cross section for elastic electron scattering from ${\mathrm{He}}^{4}$ at values of ${q}^{2}$, the four-momentum transfer squared, ranging from 0.5 to 20.0 ${\mathrm{F}}^{\ensuremath{-}2}$. Previous Stanford measurements extended

The spectra of electrons scattered inelastically from 4 He have been measured at incident energies from 150 MeV to 400 MeV for scattering angles from 38° to 90°. Through the use of a liquid 4 He target, a high momentum resolution (≈0.25%) was obt

This paper is concerned with the observation that the masses of the stable particles (μ±,μ0, μ±, etc.) tend to be close to integral multiples of (3me),me being the electron mass. The probability for random mass values to cluster around integral

We have studied elastic electron scattering from 4He at values of q2, the momentum transfers squared. ranging from 0.5 fm−2 to 10.0 fm−2. Among the models which have been found to fit the new data is modified Gaussian distribution with a half den

We have searched for virtual excited states of 3 He by inelastic electron scattering at E = 200 MeV and θ = 60°. No evidence for narrow states excited with cross section greater than 3 × 10 −33 cm 2 /sr has been found for excitation energies up
