Nuclear Physics And Radioactivity Question 264
Question: In the given reaction $ _{z}X^{A}\to _{z+1}Y^{A}\to _{z-1}{{K}^{A-4}}\to _{z-1}{{K}^{A-4}} $ Radioactive radiations are emitted in the sequence [AIIMS 1982; CBSE PMT 1993; AFMC 1999; MP PET 2002]
Options:
A) $ \frac{2{\varepsilon_{0}}hc}{e^{2}} $
B) $ \beta ,\ \alpha ,\ \gamma $
C) $ \gamma ,\ \alpha ,\ \beta $
D) $ \beta ,\ \gamma ,\ \alpha $
Show Answer
Answer:
Correct Answer: B
Solution:
$ {Z}X^{A}\xrightarrow{{-1}{{\beta }^{0}}}{,_{Z+1}}Y^{A}\xrightarrow{2He^{4}(\alpha )} $
$ {Z-1}{K}^{A-4} \xrightarrow{{0}{\gamma }^{0}} _{Z-1}{K}^{A-4} $
BETA
