\(^{238}{\rm{Pu}} \to _2^4\alpha { + ^{234}}{\rm{X}} \Rightarrow {\rm{X}}\) có 234 nucleon \( \Rightarrow \) a) Sai

\(n = \frac{m}{M} = \frac{{{{11.10}^3}}}{{238}} = \frac{{5500}}{{119}}\;{\rm{mol}}\)

\({N_0} = n{N_A} = \frac{{5500}}{{119}} \cdot 6,02 \cdot {10^{23}} \approx 2,7824 \cdot {10^{25}}\)

\(\left. {{H_0} = \lambda {N_0} = \frac{{\ln 2}}{T} \cdot {N_0} = \frac{{\ln 2}}{{87,7.365 \cdot 24.60.60}} \cdot 2,7824 \cdot {{10}^{25}} \approx 6,{{97.10}^{15}}\;{\rm{Bq}} \Rightarrow {\bf{b}}} \right)\) b) Đúng

Bảo toàn động lượng \(p_\alpha ^2 = p_X^2 \Rightarrow 2{m_\alpha }{K_\alpha } = 2{m_X}{K_X} \Rightarrow {K_X} = \frac{{{m_\alpha }{K_\alpha }}}{{{m_X}}} = \frac{{4.5,49}}{{234}} = \frac{{61}}{{650}}{\rm{MeV}}\)

\(\Delta E = {K_\alpha } + {K_X} = 5,49 + \frac{{61}}{{650}} \approx 5,6{\rm{MeV}} \Rightarrow \) c) Đúng

\({P_0} = {H_0}{K_\alpha } = 6,97 \cdot {10^{15}} \cdot 5,59 \cdot 1,6 \cdot {10^{ - 13}} \approx 6,2 \cdot {10^3}W = 6,2\;{\rm{kW}} \Rightarrow \) d) Sai
