Americium-242m has a mass of 242.0595492 g/mol. It is one of the rare cases, like 180mTa, 210mBi and multiple holmium isomers, where a higher-energy nuclear isomer is more stable than the lower-energy one, Americium-242. [18]

Twenty radioisotopes of americium— 223Am, 226Am, 229Am, 230Am, and those ranging from 232Am to 247Am—have been characterized, with the most stable being 243Am with a half-life of 7,370 years, and 241Am with a half-life of 432.2 years. All of the remaining radioactive isotopes have half-lives that are less than 51 hours, and the majority of these have half-lives that are less than 100 minutes. This element also has 8 meta states, with the most stable being 242m1Am (t 1/2 = 141 years). This isomer is unusual in that its half life is far longer than that of the ground state of the same isotope.Notably, the pressure levels published by SAAMI for the commercial .223 Rem ammo were echoed in Army publications of the 1970s such as MIL-C-9963E/F. The use of M193 ball, with its traditional 55-grain FMJ bullet, continues to some extent today, largely for guns bought by Washington for overseas military aid to allies who may still be using older M16A1s. Americium-241 is the most prevalent isotope of americium in nuclear waste. [15] It is the isotope used in an americium smoke detector based on an ionization chamber. It is a potential fuel for long-lifetime radioisotope thermoelectric generators.
