latom of chIsotope is
1 129 2 124
(3
a) 112u
1129​

Answer 1

Answer:

The isotope

5

12

B having a mass 12.014 u undergoes β -decay to

6

12

C ,

6

12

C has an excited state of the nucleus (

5

12

C

∗

) at 4.041 MeV above its ground state. If

5

12

B decays to

6

12

C

∗

, the maximum kinetic energy of the β-particle in units of MeV is

(1 u = 931.5 MeV/c

2

, where c is the speed of light in vacuum).
