摘要：

The emission bands of helium hydride near 5500 and 6400 Å were analyzed for 4HeH, 3HeD, and 4HeD. They are assigned to the emission of the coupled states D 2Σ +, (3d, ℒ = 2) and (for the deuterides) C 2Σ +, v = 3 to the A 2Σ+ (5500 Å) and B 2Π (6400 Å) states. The 3d, ℒ = 2 state is treated as pure Hund's case (d). The coupling of the electronic states is homogeneous and described by constant matrix elements. Only in the case of 4HeH, strong predissociation of the D state was observed for N′≥ 3. The emission spectra were observed after neutralization of a fast (15 keV) mass-selected HeH+ beam in potassium vapor. © 1990 American Institute of Physics.
