Scaled AMO calculations on the hydrogen molecule. III. The 1s2s 3∑ state

The potential energy curve for the 1s2s ³∑ state of the hydrogen molecule is calculated in a scaled version of the AMO approximation. Deviations from a simple potential curve occur. The agreement with experimental data is found to be better for the present state than for the 1sσ2pσ ¹∑ state studied in a previous paper.
