(Received February 22, 1988)
Recent rotation-vibration approaches to quasi-molecular states are
examined. It is pointed out that an approximation made to derive the
rotation-vibration spectrum is not valid and misleading in the nuclear

- A. Faessler claimed, in the private communication: “The states above 6.3 MeV are in the continuum. Our description should not be taken seriously for these states. However, the parameters of this potential determined by us will remain the same, even if we do not take them into account.” But the present authors wonder what physical meaning their potential can have, which reproduces only the resonances observed below 6.3 MeV but fails completely for those above 6.3 MeV. Note also that there is no characteristic difference between the resonances above and below 6.3 MeV, but they are known to have the common features of molecular resonances such as widths, decay properties and so on!
