A new seaborgium isotope may unlock the path to discovering even shorter-lived superheavy nuclei through K-isomer states. An ...

Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are other isotopes). For nuclear power reactors or weapons, we need to change the isotope proportions.

Researchers at Chalmers University of Technology in Sweden carried out nuclear fission reactions in 100 different types of ...

Most elements in nature have mixtures of isotopes, Broido explained. For example, naturally occurring boron has two isotopes, approximately 20 percent boron-10 and 80 percent boron-11. ... estimation ...

The number of protons defines what element it is, with the number of protons and neutrons combined defining the isotope number. An atom with 6 protons is carbon, and if it also has 6 neutrons it ...

When we dig uranium out of the ground, 99.27% of it is uranium-238, which has 92 protons and 146 neutrons. Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are ...

THEORETICAL investigations of the interaction of protons and neutrons have been given by Wigner, Heisenberg and Major ana. A very valuable check on their conclusions is provided by the study of ...
