Dispersive refraction of different light-to-heavy materials at MeV $\gamma$-ray energies

M. M. Günther, A. V. Volotka, M. Jentschel +4

The dispersive behavior of materials with atomic charge numbers varing from $Z=4$ (beryllium, Be) to $Z=82$ (lead, Pb) was investigated experimentally and theoretically at $\gamma$-…
