Abstract:
Crystals of bacteriophage Qbeta have been obtained by the vapor-diffusion technique. The crystals diffract to at least 3.5 A resolution. The crystal space group is C222(1) with the unit-cell parameters a = 478, b = 296, c = 477 A, alpha = beta = gamma = 90 degrees. The unit cell contains four virus particles. A pattern of systematic extinctions has been used to deduce the packing of the particles in the cell. A limited data set to 3.9 A resolution has been collected, and the predicted position has been confirmed by the self-rotation and the Patterson functions.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
