On the Multiple Spectrum of a Problem for the Bessel Equation with Squared Spectral Parameter in the Boundary Condition

We consider a problem for the Bessel equation of integer order with complex physical and spectral parameters in the boundary condition. The spectral parameter occurs quadratically in the boundary condition. The basis property of the eigenfunction system is studied.
