We study an eigenvalue equation derived from a model for electrons in a ballistic regime moving in a carbon nanotube or in a graphene structure. We sow that some conclusions drawn from numerical calculations are trivial and can be predicted beforehand by means of well known theoretical analytical expressions and theorems. In addition to it, we show that the variational method is suitable for the calculation of excited states and that the numerical integration method based on Wronskians already applies to the problem, contrary to what was previously stated. In particular, the Wronskian method proves suitable for estimating the range of values of the model parameter for which the potential supports more than one bound state.
