Skyrme-like hyperon-nucleon potentials are derived from G-matrix calculations and shown to reproduce well the {Lambda} single-particle spectra of hypernuclei measured at BNL and KEK. Previously known potentials are reexamined systematically. The fit of the spectra can restrict the radii of {Lambda} orbits in hypernuclear ground states, {Lambda} well depth and effective mass in nuclear matter, and polarization of nuclear cores caused by hyperon rather tightly. The implications of the {Lambda}N spin-orbit force to the spectra are considered. Hartree-Fock calculations of binding energies of {sub {Lambda}{Lambda}}{sup 13}B with density-dependent G-matrix {Lambda}{Lambda} potentials are presented, taking note of the core-rearrangement effects induced by {Lambda}N interactions. {copyright} {ital 1997} {ital The American Physical Society}
