The sequence of stepwise decay of a radioactive nucleus is: DoversetalphararrD_1oversetbetararrD_2 If the atomic number and mass number of D_2 and 71 and 176 respectively, what are their corresponding values for D?

The unit of length convenient on the nuclear scale is a fermi : 1 f = 10 ^-15 m . Nuclear sizes obey roughly the following empirical relation :- r=(r_0A)^(1/3) where ris the radius of the nucleus, Aits mass number, and r_o is a constant equal to about, 1.2 f. Show that the rule implies that nuclear mass density is nearly constant for different nuclei. Estimate the mass density of sodium nucleus. Compare it with the average mass density of a sodium atom obtained in Exercise. 2.27.
