✦ Synopsis

We present a microscopic calculation of the electron-bubble radius and energy in liquid 3He at zero applied pressure. The two-particle distribution function is approximated as input by the radial distribution function of bulk 3He. The theoretical value of the radius at 14 ~ is about 30% below the experimental value obtained from mobility measurements. The model presented here predicts an electron-bubble surface that is less sharp compared to what was obtained by Shih and Woo for the bubble in 4He. Around the bubble the matter density profile appears to be characterized by a high-density region which is about one atomic layer in thickness. The density peak at the bubble surface exceeds the bulk density by about 10%. The approximation schemes are discussed and the source of discrepancy with experiment speculated upon.
