Line shapes for the Rb D₁ (5²S_1/2 ↔ 5²P_1/2) and D₂ (5²S_1/2 ↔ 5²P_3/2) transitions with ⁴He and ³He collisions at pressures of 500–15,000 Torr and temperatures of 333–533 K have been experimentally observed and compared to predictions from the Anderson–Talman theory. The ground X²Σ⁺_1/2 and excited A²Π_1/2, A²Π_3/2, and B²Σ⁺_1/2 potential energy surfaces required for the line shape predictions have been calculated using a one-electron …
