(a) Write the basic nuclear process involved in the emission of β+ in a symbolic form, by a radioactive nucleus.
(b) In the reactions given below :
(i) ‌611C→‌yzB+x+v
(ii) ‌612C+‌612C→‌a20‌Ne+‌bc‌He
Find the values of x,y , and z and a,b and c .

Solution:

(a) Basic nuclear process
(b) (i) value of x,y,z
(ii) value of a,b,c
(a) Basic nuclear reaction
P→n+e++v
(b) (i) x=β+∕‌10e,y=5,z=11
(ii) a=10,b=2,c=4
