It is pointed out that a recent work by Nakaichi et al. on few-atom 3He–4He mixed molecules is based on incorrect values of Θ2/M3 and Θ2/M4, where M3 and M4 are the masses of the 3He and 4He atoms. This is shown to affect their conclusion on the 3He(4He)2 system seriously.

The interaction between two 3He atoms is calculated by taking into account the backflow effect of 3He by the 4He in the 3He-4He mixture. The effect contributes solely to the P wave part of the interaction. The repulsive S wave part of the contact interaction contributes to the exchange interaction between the 3He atoms, while the direct one phonon exchange interaction contributes both to the S and P wave attractive interactions. The overall contribution to the attractive interaction is dominated by the P wave part and the superfluidity in the P wave is more predominant than in the S wave for the 5
