100050

100050 refers to the isotope tin‑100, with an atomic number of 50 and a mass number of 100. The nucleus consists of 50 protons and 50 neutrons, making it a doubly magic nucleus because both proton and neutron numbers are magic numbers in the nuclear shell model. This configuration gives tin‑100 a highly stable internal structure despite it lying far from the valley of beta stability, where most stable isotopes of tin are found between mass numbers 112 and 124.

Tin‑100 is proton‑rich and was first produced in the early 21st‑century through heavy‑ion collisions in large accelerator facilities. Its half‑life is extremely short, on the order of a few microseconds, and it decays primarily by beta‑plus emission or by direct proton emission. Studies of this isotope have provided valuable insights into the behavior of nuclei at the limits of stability and into the evolution of shell structure away from the valley of beta stability.

Because of its doubly magic nature, tin‑100 serves as a benchmark for testing nuclear models and for refining interactions between protons and neutrons in the nucleus. Researchers continue to investigate its properties through advanced detection techniques, which help improve the accuracy of theoretical predictions for exotic nuclei and enhance our understanding of the processes that shape the synthesis of elements in stars.
