Wave particle dualtiy and neutron diffraction

Click For Summary
SUMMARY

To observe neutron diffraction effects with a neutron kinetic energy of 10 MeV, the size of the target object must be comparable to the wavelength of the neutrons. The de Broglie wavelength can be calculated using the equation λ = h/p, where h is Planck's constant and p is the momentum of the neutron. For 10 MeV neutrons, the corresponding wavelength is approximately 0.12 nanometers. Suitable natural targets for demonstrating this phenomenon include materials like graphite or other crystalline structures that can accommodate this scale.

1. A neutron has a kinetic energy of 10MeV. What size object is necessary to observe neutron diffraction effects?

Is there anything in nature of this size that could serve as a target to demonstrate the wave number of 10MeV neutrons?

K= 10MeV or 1.602 x 10^-12J Mass of neutron = 1.675 x 10^-27kg

This probably should be a simple problem but for some reason I've not been able to figure out how to solve for the size of the required object. What part of that problem gives the info needed to solve for the size of an object required to observe diffraction?

Thanks!
