In Geiger-Marsden scattering experiment, the trajectory of -particles in Coulomb’s field of a heavy nucleus is shown in the figure.
(a) What do ‘b’ and represent in the figure ?
(b) What will be the value of ‘b’ for (i) , and (ii) ?
a) b represents impact parameter and represents scattering angle
(b) impact parameter is larger
the impact parameter is zero.
