amerisium241tä

Americium-241tä is a hypothetical isotope of americium. Americium (Am) is a transuranic radioactive metal element with atomic number 95. Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. The most stable known isotopes of americium are americium-243, with a half-life of 7370 years, and americium-241, with a half-life of 432.2 years. The designation "tä" is not a standard isotopic notation. Standard notation for isotopes includes the element name or symbol followed by the mass number (e.g., Americium-241 or Am-241). The addition of "tä" does not correspond to any recognized system for specifying isotopic properties such as nuclear spin or isomeric state. If "tä" were intended to represent a specific characteristic, such as a meta-stable isomeric state, it would typically be indicated with an "m" following the mass number, like Am-241m. Without further context or clarification, americium-241tä is considered an undefined or incorrectly notated isotopic species. Its properties, if it were a valid designation, would likely be very similar to americium-241, as the mass number would remain the same, unless "tä" implied a significant change in nuclear structure beyond that of a standard isotope. The primary isotope of americium used in smoke detectors is americium-241, which emits alpha particles and gamma rays.
