The number of `beta` - particle emitted during the change `""_(a) X^(c) to ""_(a) Y^(b)` is :

A

`(a- b)/(4)`

B

`d + [ (a- b)/(2)]`

C

`d- a + [(c- d)/(2)]`

D

`d + [ (a- b)/(2)] - c`

Text Solution

Verified by Experts

The correct Answer is:
C
`""_(a) X^(c) to ""_(d) Y^(b) + x (""_(2) He^(4)) + y (""_(-1) beta^(0)) , x = ((c- b)/(4))`
`a = d + 2x - y , y = d + 2x -a , y = d + 2 ((c - b)/(4)) - a , , y = [d - a + (c- b)/(2)]`
