48Ti

48Ti is a stable, naturally occurring isotope of the element titanium (Ti). It has 22 protons and 26 neutrons, giving a mass number of 48. The atomic mass of 48Ti is 47.9479463 u. It is the most abundant titanium isotope, accounting for roughly 74% of natural titanium.

As an even-even nucleus (Z = 22, N = 26), the ground-state spin of 48Ti is 0 and its parity is positive. Its stability means there is no radioactive decay associated with this isotope under normal conditions, and it remains in Earth's crust as part of titanium minerals.

Natural occurrence and isotopic composition: In nature, titanium consists of several stable isotopes, with 48Ti being the dominant one, followed by smaller quantities of 46Ti, 47Ti, 49Ti, and 50Ti. The exact relative abundances vary slightly by source, but 48Ti remains the principal contributor to titanium’s atomic weight.

Applications and significance: The high natural abundance and stability of 48Ti make it a common reference isotope for isotopic abundance measurements and isotope-ratio mass spectrometry. It also serves as a material and calibration reference in various fields, including materials science and nuclear physics experiments, where titanium compounds or targets may be employed.
