...isotope-unlike many of its transuranium counterparts -appeared to be in no rush to disappear. The California scientists eventually determined that its half life (the time in which half the atoms of an element decay) was nearly two months. This compared, for example, with only eight seconds for lawrencium 257, until now the heaviest of the known atoms...
...detectors signaled the capture of an alpha particle charged with 8,600,000 electron volts of energy. Nuclear theory predicts that this is just the particle that would be emitted during the disintegration of element 103. The scientists estimated its half-life as eight seconds, and they named it lawrencium, after Ernest Lawrence, founder of their laboratory...
