Question

The following transmutations are used to produce transuranium elements. Identify the nuclide or particle designated as X. $$(i) ^{242}Cm$$(α,$$n)X(ii) ^{10}B(n$$, $$X)^{7}Li$$

Accepted Answer

(i) X $$is ^{245}$$_{98}Cf. The long-hand reaction $$is ^{242}$$_{96}Cm $$+ ^{4}$$_{2}He → ^{245}_{98}Cf $$+ ^{1}$$_{0}n.  (ii) X $$is ^{4}$$_{2}He. The long-hand reaction $$is ^{10}$$_{5}B $$+ ^{1}$$_{0}n → ^{7}_{3}Li $$+ ^{4}$$_{2}He.

Answer

(i) X $$is ^{246}$$_{98}Cf. The long-hand reaction $$is ^{242}$$_{96}Cm $$+ ^{4}$$_{2}He → ^{246}_{98}Cf $$+ ^{1}$$_{0}n.  (ii) X $$is ^{4}$$_{2}β. The long-hand reaction $$is ^{10}$$_{5}B $$+ ^{1}$$_{0}n → ^{7}_{3}Li $$+ ^{4}$$_{2}β.

Answer

(i) X $$is ^{246}$$_{94}Pu. The long-hand reaction $$is ^{242}$$_{96}Cm $$+ ^{4}$$_{2}He → ^{246}_{94}Pu $$+ ^{1}$$_{0}n.  (ii) X $$is ^{4}$$_{2}β. The long-hand reaction $$is ^{10}$$_{5}B $$+ ^{1}$$_{0}n → ^{7}_{3}Li $$+ ^{4}$$_{2}β.

Answer

(i) X $$is ^{246}$$_{94}Pu. The long-hand reaction $$is ^{242}$$_{96}Cm $$+ ^{4}$$_{2}He → ^{246}_{94}Pu $$+ ^{1}$$_{0}n.  (ii) X $$is ^{1}$$_{1}H. The long-hand reaction $$is ^{10}$$_{5}B $$+ ^{1}$$_{0}n → ^{7}_{3}Li + X $$is ^{1}$$_{1}H.
