Which does not take place by `alpha` disintegration ?

A

`""_(92)U^(238) to ""_(90)U^(234)`

B

`""_(90)TH^(232)to ""_(88)Ra^(228)`

C

`""_(88)Ra^(226) to ""_(86)Rn^(222)`

D

`""_(83)Bi^(213)to ""_(84)Po^(213)`

Text Solution

Verified by Experts

The correct Answer is:
D
`""_(83)Bi^(213)to ""_(84)Po^(213)+""_(-1)e^(0)`
It occurs by `beta`-decay.
