Fractional Cumulative Yields of ¹⁰³Mo, ¹⁰⁵Mo and ¹⁰⁶Mo from Thermal-Neutron Induced Fission of ²³⁵U

The influence of pairing and nuclear structure on the thermal-neutron-induced fission of235U

“…If we multiply the yields in Table 1 by the corresponding mass yields [17], the total Tc-yield observed in fission product masses A < 107 at the most probable kinetic energy Ep is (0.134-0.05)%. Thus our earlier results [7] as well as previous radiochemical measurements [19,20], which gave very low Tc-yields, are supported by the present measurements. At present it is difficult to decide whether this sudden drop in the yield from Z = 42 to Z =43 is due to a stable Z = 50 shell in the complementary heavy fragments.…”

Discovery of rubidium, strontium, molybdenum, and rhodium isotopes

“…"Fission fragments were separated using the fragment separator FRS tuned in an achromatic mode and identified by event-by-event measurements of ∆E-Bρ-ToF and trajectory." During the experiment, five counts for 122 Rh were recorded.…”

Nuclear Charge Distribution in the Spontaneous Fission of 252Cf: Isotopic Yield Distribution for Technetium Isotopes

“…The chemical yield was found to be ~ 60%. [23,24] To obtain the fractional cumulative yields of 101 Mo, ,03 MO, 104 MO and ,0S Mo, the Tc was separated from its precursor Mo by adsorption of Tc0 4 on a preformed precipitate of tetraphenyl arsonium chlorate [(C 6 H s ) 4 As]C10 4 This precipitate is formed when a dilute solution of HC10 4 is added to a [(C 6 H S ) 4 As]Cl solution. The chemical yield of Tc was determined using 99m Tc tracer.…”
