234Pa skapas genom sönderfall av 238U enligt nedanstående sönderfalls-schema. 238U → 234Th + α. 234Th → 234Pa + β-. 234Pa → 234U

The yields of γ-quanta with the energy of 73.9 keV, emitted by 234Pa nuclei produced by the β-decay of 234Th in uranium metal and uranyl nitrate matrices, differ by 26 ± 8%, which suggests the corresponding difference in the probability of the low-energy isomeric transition of 234Pa in these matrices.

The decay scheme leading to the formation of 234Pa in the solution of uranium salt is as follows: 238U 234Th 234Pa 234U. half-life: 4.5 ( 109 24.1 to be found 2.5 ( 105 The fission probability of 234Pa and 236U compound nuclei produced in 232Th(6Li, α)234Pa and 232Th(6Li, d)236U transfer reaction channels has been measured at Elab=38.0 MeV in the excitation The yields of γ-quanta with the energy of 73.9 keV, emitted by 234Pa nuclei produced by the β-decay of 234Th in uranium metal and uranyl nitrate matrices, differ by 26 ± 8%, which suggests the corresponding difference in the probability of the low-energy isomeric transition of 234Pa in these matrices. 234pa (UZ) ,1r.1s%l 6.7h i 13 a 230fh.

Nov 1, 2009 Results indicate a convergence of the particle size distributions of OC and 234Th during the winter-spring bloom period (January–March, 2007).

Show transcribed image text. 234Pa is extracted from a solution containing the parent 234Th and ’grandparent’ 238U with which it is in equilibrium. Once extracted the decay of 234Pa can be recorded. The recovery of 234Pa can be followed in the aqueous layer if desired. About 95% of the protactinium is removed together with some uranium when the bottle is shaken. yiluxiangxi13: upyznvfrdaulgnzmynyuWWw)234pa)com【街头霸王嘉米】gbjsjjsbmuitbhkzdzqqpqwvpdhudpWWw)234pa)com【街头霸王嘉米 The yields of γ-quanta with the energy of 73.9 keV, emitted by 234Pa nuclei produced by the β-decay of 234Th in uranium metal and uranyl nitrate matrices, differ by 26 ± 8%, which suggests the corresponding difference in the probability of the low-energy isomeric transition of 234Pa in these matrices.
