Scientists at Ludwig-Maximilians-Universit=E4t in Munich and the Max Planck Institute of Quantum Optics in Garching have opened up a new chapter in optics: in experiments with gamma rays at the Institut Laue- Langevin (ILL) in Grenoble they have proven that these extremely high- energy electromagnetic waves can be focused by lenses like conventional light =96 the researchers have thus refuted a fundamental assumption of theoretical physics that had been valid for decades. Their discovery will make a great many new applications possible in medicine and materials research, for example.
HIGH-ENERGY RADIATION IS REFRACTED SETTING THE STAGE FOR GAMMA OPTICS

Here is a direct link to the actual research rather than some garbled new age hippy version that seems to be out on the web.
The real science isn't quite as exciting as the breathless reporting of it by clueless journalists.
I was a bit puzzled at first the gamma ray astronomy conference isn't until July so I looked for it in the wrong place.
Careful choice of isotopes so that they are more or less pure single line emitters of a particular gamma ray energy. There is always a slight tail of lower energy phtons due to recoil and scattering.
Co60 isn't monochromatic since there are two sharp peaks but you can get the general idea.
Thanks! What is a bit confusing, is the business in the second article, "The deflection of a monochromatic ? beam..". Monochromatic? Gamma lasers???????????????
