    Gott in Himmel! German scientists shine an X-ray through solid iron<br /> <br /> Updated: 18:01 GMT, 8 February 2012 <br>

    <br /><br /> <br>German scientists have successfully shone an X-ray through iron. <br /><br><br>A team of scientists at the PETRA III accelerator in Hamburg-Bahrenfeld made the nuclei of iron atoms transparent using a high-powered X-ray light source and platinum mirrors.

    <br /><br><br>The discovery – bouncing X-rays around the iron to make X-rays travel through  could pave the way for futuristic ‘quantum’ computers. <br /><br> A team of scientists at the PETRA III accelerator in Hamburg-Bahrenfeld made the nuclei of iron atoms transparent using a high-powered X-ray light source and platinum mirrors<br> <br>The scientists positioned two thin layers of atoms in an optical cavity, an arrangement of two parallel platinum mirrors that reflect X-rays.<br><br>The light ‘bouncing’ between layers makes the layer of iron transparent.

    <br /><br><br>The discovery could have important implications for future ‘quantum’ computers. <br /><br><br>During the experiment, light is also slowed down from its normal speed of 300,000 metres per second to just a few metres per second.<br><br> The scientists, led by Dr.
    Ralf Röhlsberger, http://www.noclegi-pracownicze-augustow.online are now looking at ‘whether it is possible to use this effect scientifically. ‘<br /><br><br>The team says, ‘A possible application is the storage of information with extremely slow or even stopped light pulses.’  <br><br> The two layers of iron-57 atoms, each approximately three nanometres thick, were kept in position between the two platinum mirrors by carbon, which is transparent for X-ray light of the wavelength used.

    <br /><br><br>This kind of sandwich with a total thickness of only 50 nanometres is irradiated under very shallow angles with an extremely thin X-ray beam from the PETRA III synchrotron light source. <br /><br><br>Within this mirror system, the light is reflected back and forth several times, generating a standing wave, a so-called resonance.
    <br /><br><br>When the light wavelength and the distance between both iron layers are just right in proportion, the scientists can see that the iron becomes almost transparent for the X-ray light. <br /><br><br><br /><br /><br>
