A high finesse standing-wave cavity mode resonantly interacting with a beam of two-level {sup 138}Ba atoms is weakly driven by a tunable laser. Transmitted and sidelight scattered line shapes are recorded. With mean intracavity atomic number, {l_angle}{ital {bar N}}{r_angle}{approx_equal}1, we observe one-, two-, and three-peaked line shapes for strong coupling. In addition, two-peaked spectra observed in intermediate coupling demonstrate that line-shape splitting is not necessarily indicative of oscillatory atom-cavity energy exchange. Several atoms are required for {l_angle}{ital {bar N}}{r_angle}{approx_equal}1, so this is not a true single-atom regime. {copyright} {ital 1996 The American Physical Society.}
