PHY4 HELP - de Broglie wavelength

Discuss briefly whether neutrons or electrons travelling at this speed would be more suitable for atomic diffraction studies.

speed = 6.3 x 10^6(ms^-1)

de Broglie wavelength for netrons travelling at this speed & have a mass of 1.67 x 10^-27(kg) is 6.3x10^-14(m)

well what is the interatomic distance? Use the particle whose wavelength is similar to this distance.

you aren't given that kind of information, everything is included in the question + previous worked out wavelength is given above.

i am tempted to say neutrons because the wavelength is quite large if electrons are used. But i am not sure though.

john !!

nucleus diameter is 10^-15, atomic diameter is 10^-10 approx.
