Question

Write missing symbols, denoted by `x`, in the following nuclear reactions:
(a) `B^(10)(x,alpha)Be^(8)`,
(b) `O^(17)(d,n)x`,
(c )`Na^(23)(p,x)Ne^(20)`,
(d)`x(p,n)Ar^(37)`.

Answer 1

(a) The particle `x` must carry two nucleous and a unit of positive charge. The reaction is
`B^(10)(d, alpha)B_(e )^(8)`
(b) The particle `x` must contain a proton in addition to the constituents of `O^(17)`. Thus the reaction is
`O^(17)(d,n)F^(18)`
(c ) The particle `x` must carry nucleon number `4` and two units of `+ve` charge. Thus the particle must be `x-alpha` and the reaction is
`Na^(23)(p, alpha)Ne^(20)`
(d) The particle `x` must carry mass number `37` and have one unit less of positive charge. Thus `x=Cl^(37)` and the reaction is
`Cl^(37)(p,n)Ar^(37)`
