MxMx and MyMy denote the atomic masses of the parent and the daughter nuclei respectively in radioactive decay. The Q-Q-value for a β−β− decay is Q1Q1 and that for a β+β+ decay is Q2.Q2. If meme denotes the mass of an electron, then which of the following statements is correct?
1. | [Q1=(Mx−My)c2 and Q2=[Mx−My−2me]c2[Q1=(Mx−My)c2 and Q2=[Mx−My−2me]c2 |
2. | [Q1=(Mx−My)c2 and Q2=(Mx−My)c2[Q1=(Mx−My)c2 and Q2=(Mx−My)c2 |
3. | [Q1=(Mx−My−2me)c2 and Q2=(Mx−My+2me)c2[Q1=(Mx−My−2me)c2 and Q2=(Mx−My+2me)c2 |
4. | [Q1=(Mx−My+2me)c2 and Q2=(Mx−My+2me)c4 |
