Question

Experimental procedure of Neutron.

Please tell. ​

Answer 1

Answer:

Explanation:In 1932, the physicist James Chadwick conducted an experiment in which he bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. The resulting radiation showed high penetration through a lead shield, which could not be explained via the particles known at that time.

Explanation:

What are neutrons? Our bodies are actually made of a large number of neutrons, as shown in the figure below. Roughly 70% of the human body is made up of water. A water molecule is composed of one oxygen atom and two hydrogen atoms, an oxygen atom is composed of an oxygen nucleus and eight electrons, and an oxygen nucleus is composed of eight protons and eight neutrons

The size of a neutron is 0.000000000000001 m (that is, a thousand trillionths of a meter). If the cross-section of a hair were enlarged to the size of the earth, a neutron would have a cross-section about the size of a hair. Neutrons are very small particles, and are known to exhibit strange characteristics whereby they behave like waves, even though they are particles.

The most common experiments conducted using neutrons are scattering experiments; in them, a neutron beam is targeted at the substance (sample) under investigation and the manner in which they fly off (scatter) is measured. A scattering pattern showing the structure of the sample on an atomic or molecular scale is produced due to the wave-like characteristics of the neutrons involved in the scattering. Atomic distributions in crystals and the structures of liquids and gasses can be investigated by carefully analyzing these scattering patterns. Like X-ray radiograph, neutrons can also be used to observe a sample's interior. This experimental method is known as imaging.

Experiments similar to those conducted with neutrons can be performed with X-rays or electron beams; however, information that cannot be obtained using X-rays or electron beams can be extracted with neutrons by taking advantage of their following characteristics:
