The classical separation theorems regarding the relative position of the zeros of two consecutive orthogonal polynomials, or of the positive zeros of two consecutive Bessel Functions, are well known. Less well known is a theorem of Bôcher and Porter (1, p. 237), which states that the positive zeros of three consecutive Bessel Functions occur in cyclic order.
