Query: Diffraction of a binary non-Pisot inflation tiling   A one-parameter family of binary inflation rules in one dimension is
considered. Apart from the first member, which is the well-known Fibonacci
rule, no inflation factor is a unit. We identify all cases with pure point
spectrum, and discuss the diffraction spectra of the other members of the
family. Apart from the trivial Bragg peaks at the origin, they have purely
singular continuous diffraction.
