44Ti44Sc

44Ti44Sc refers to an atomic nucleus with 44 protons and 44 neutrons. This specific isotope combination is known as Titanium-44 (⁴⁴Ti) which decays into Scandium-44 (⁴⁴Sc). Titanium-44 is a radioactive isotope with a relatively long half-life of approximately 60 years. It is primarily produced in supernovae, the explosive deaths of massive stars. When ⁴⁴Ti decays, it emits a positron and a neutrino, transforming into ⁴⁴Sc. Scandium-44 is also radioactive, possessing a shorter half-life of around 3.9 hours. It decays through electron capture, releasing gamma rays, and eventually forms stable Calcium-44 (⁴⁴Ca). The decay chain of ⁴⁴Ti to ⁴⁴Sc to ⁴⁴Ca is of interest in astrophysics for understanding nucleosynthesis in stellar environments and for calibrating certain astrophysical observations. Due to its half-life and decay properties, ⁴⁴Ti has also been explored as a potential medical radioisotope, though its production and application are complex.
