Source A transuranium element, only a few atoms of hassium have ever been made, and it will probably never be isolated in observable quantities. It is created by a so-called " soft fusion"method, in which a target of lead is bombarded with atoms of iron.

Mass number of the longest-lived isotope of hassium from Phys. ... The value enclosed in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However three such elements (Th, Pa, and U) do have a characteristic terrestrial isotopic composition, and for these an atomic weight is tabulated.
