An isotope of the element with atomic number 97 has been discovered as a product of the helium ion bombardment of americium. This isotope decays with the emission of alpha-particles of maximum energy 6.72 Mev (30 percent) and it emits lower energy alpha-particles of energies 6.55 Mev (53 ...
The lanthanide series of metals includes the 15 elements with atomic numbers 57–71, plus yttrium (atomic number 39). The lanthanides occur in the earth's crust at concentrations exceeding some commonly used industrial elements making the term ‘rare earths’ something of a misnomer. For example...
