Abstract
The problem of finding proper quantal operators for the time of arrival, when the source is at infinite distance from the detector, is investigated. It is shown that at least two Hermitian operators can be constructed which, in the Hilbert space of positive energy spectrum, are self-adjoint. The spectra of these operators are continuous and their eigenfunctions form an orthonormal set.
