Question 284: Atoms & Nuclei

Question

If the binding energy per nucleon in $${}_3^7Li$$ and $${}_2^4He$$ nuclei are $$5.60$$ $$MeV$$ and $$7.06$$ $$MeV$$ respectively, then in the reaction 
$$$p + {}_3^7Li 	o 2\,{}_2^4He$$$
energy of proton must be

Accepted Answer

Let $$E$$ be the energy of proton, then
$$E + 7 	imes 5.6 = 2 	imes \left[ {4 	imes 7.06} ight]$$
$$ \Rightarrow E = 56.48 - 39.2 = 17.28MeV$$

Answer

$$28.24$$ $$MeV$$

Answer

$$17.28$$ $$MeV$$

Answer

$$1.46$$ $$MeV$$

Answer

$$39.2$$ $$MeV$$
