Uran-234

Uran-234 quyidagi parchalanishlar natijasida hosil boʻladi:

• Nuklidning β⁺-parchalanishi ²³⁴Np (yarim yemirilish davri 4,4(1)kun):

${\displaystyle \mathrm {^{234}_{93}Np} \rightarrow \mathrm {~_{92}^{234}U} +e^{+}+{\nu }_{e};}$

• Nuklidning β⁻-parchalanishi ²³⁴Pa (yarim yemirilish davri 6,70(5) soat):

${\displaystyle \mathrm {^{234}_{91}Pa} \rightarrow \mathrm {^{234}_{92}U} +e^{-}+{\bar {\nu }}_{e};}$

• Alfa parchalanishi nuklidi ²³⁸Pu (yarim yemirilish davri 87,7(1)^[1] yil):

${\displaystyle \mathrm {^{238}_{94}Pu} \rightarrow \mathrm {^{234}_{92}U} +\mathrm {^{4}_{2}He} .}$

Uran-234 ning parchalanishi quyidagi yoʻllar bilan sodir boʻladi:

• Alfa parchalanishi ²³⁰Th ga (ehtimol 100 %^[1], parchalanish energiyasi 4,857,7 (7) keV)

${\displaystyle \mathrm {^{234}_{92}U} \rightarrow \mathrm {^{230}_{90}Th} +\mathrm {^{4}_{2}He} ;}$

chiqarilgan α-zarrachalar energiyasi 4722,4 keV (28,42 % hollarda) va 4774,6 keV (71,38 % hollarda)^[2].

• Spontan parchalanish (ehtimollik 1,73(10)×10⁻⁹ %)^[1].
• Klaster yemirilishi ²⁸Mg ga (parchalanish ehtimoli 1,4(3)×10⁻¹¹ %^[1] , boshqalarga koʻra 3.9(10)×10⁻¹¹ %^[3]):

${\displaystyle \mathrm {^{234}_{92}U} \rightarrow \mathrm {^{206}_{80}Hg} +\mathrm {^{28}_{12}Mg} .}$

• Klaster yemirilishi ²⁴Ne va ²⁶Ne nuklidlarini hosil qilish uchun (parchalanish ehtimoli 9(7)×10⁻¹²%^[1], boshqa manbalargalarga muvofiq 2.3(7)×10⁻¹¹%^[3]):

${\displaystyle \mathrm {^{234}_{92}U} \rightarrow \mathrm {^{210}_{82}Pb} +\mathrm {^{24}_{10}Ne} ;}$

${\displaystyle \mathrm {^{234}_{92}U} \rightarrow \mathrm {^{208}_{82}Pb} +\mathrm {^{26}_{10}Ne} .}$
