Consider two arbitaray decay equation and mark the correct alternative` s` given below. (i) `._(92)^(230)U rarr n+._(92)^(229)U` (ii)`._(92_^(230)U rarr P +._(91)^(229)Pa`
Given: `M(._(92)^(230)U) =230.033927 u,M(._(92)^(229)U)=229.03349 u, m_(n)=1.008665u`, `M(._(91)^(229)Pa) =229.032089, m_p`=1.007825, 1 am u =931.5 MeV`.

A

Only decay (i) is possible.

B

Only decay (ii) is possible.

C

Both decay are possible.

D

Neither of the two decay is possible.

Text Solution

Verified by Experts

The correct Answer is:
d

For decay (i):
`Q=[230.033927 -229.033496 - 1.008665]xx931.5`
`= -7.7 MeV`
(ii): `Q=[230.033927 - 229.032089 -1.007825] xx 931.5`
`= -5.6 MeV`
As `Q` is negative for both the decays, so none of the decay is allowed.
