U235tä

U235tä is a theoretical isotope of uranium. The standard notation for this isotope is Uranium-235, or U-235. The "tä" in U235tä is not a recognized part of isotopic notation in nuclear physics or chemistry. Standard notation consists of the element symbol (U) followed by the mass number (235).

Uranium is a chemical element with the symbol U and atomic number 92. It is a dense, silvery-white metal. Naturally occurring uranium consists of two isotopes: U-238, which makes up about 99.3% of the total, and U-235, which accounts for about 0.7%.

U-235 is significant because it is a fissile isotope. This means it can sustain a nuclear chain reaction when it absorbs a slow-moving neutron. This property makes U-235 crucial for the operation of nuclear reactors and for the development of nuclear weapons.

The "tä" suffix does not correspond to any known scientific designation for isotopes, decay modes, or excited states. It is possible it is a typographical error, a misunderstanding of notation, or a designation used in a very specific, non-standard context. In established scientific literature, the isotope is consistently referred to as U-235.
