Calculate :
(i) mass defect of Helium `(""_(2)^(4)He)` nucleus
(ii) Obtain a relation between radius and mass number of a nucleus.
Mass of proton = 1.007276 u
Mass of neutron = 1.008665 u
Mass of `""_(2)He^(4)` nucleus = 4.001506 u
(b) What are characteristic X-rays ? How are they different from continuous X-rays Give any one difference.

Text Solution

Verified by Experts

(a) calculate `Deltam` = mass of nucleons - mass of nucleus
Binding energy = `Deltamxx931.5` (in MeV).
