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

$39.2$ $MeV$
