Question

A form of small-angle scattering using these particles can help resolve the structures of colloids. For 10 points each:

[10e] Identify these subatomic particles that elastically scatter with atomic nuclei. Isotopes of the same element differ in the number of these chargeless particles.

ANSWER: neutrons [accept small-angle neutron scattering or SANS]

[10h] The quality of SANS scattering is a function of I and this other quantity. This quantity gives information on the overall size of a molecule and is multiplied by q on the x-axis of a Guinier (“gheen-YAY”) plot.

ANSWER: radius of gyration [prompt on Rg]

[10m] SANS provides lower-resolution information than this other scattering technique used to solve atomic protein structure. The phase problem must be solved in this technique which may employ the Patterson function.

ANSWER: X-ray crystallography [or XRC; accept X-ray diffraction or XRD]
