        abstract = {A theory of the exciton spectrum in the cylindrical nanotube is proposed in the paper. The spectrum of bound
exciton states in a nanotube is obtained in the framework of rectangular potentials and electron and hole e?ective
masses within the Bethe method.
The energy of the exciton ground state calculated for the InP/InAs/InP nanosystem is in good correlation
with experimental data.}
