influences only nucleons close to it is also referred to as saturation
property of the nuclear force (iii) A very heavy nucleus, say A = 240, has lower binding energy per
nucleon compared to that of a  nucleus with A = 120 Thus if a
nucleus A = 240 breaks into two A = 120 nuclei, nucleons get more
tightly bound
