Recommendation Distance Of Closest Approach

If the momentum of the alpha-particle is 2p the corresponding distance of closest approach is 1 4r 2 2r 3 2r 4 r4.

Distance of closest approach. A 1 MeV proton is sent against a gold leaf Z 79. Distance of closest approach between two atoms is 173Å. 1973 MeV fm137For example the distance of closest approach is therefore given by 1973zZ fm137T where the kinetic energyTis given in MeV.

Calculate the distance of closest approach between an alpha particle of energy 55 MeV 55x10 6 x16x10 -19 if the charge on the gold nucleus is 79e 79x16x10 -19 C and the charge on the alpha particle is 2e 2x16x10 -19 C Using d c 14πε oqQE α we have d c 9x10 9 x 2x16x10 -19 x79x16x10 -1955x10 -13 66x10 -14 m. A detailed class on the Distance of the closest approach. The minimum distance between the centre of the nucleus and the alpha particle just before it gets reflected back through 180 is defined as the distance of closest approach r also known as contact distance.
