Neutron Capture At High Neutron Flux
The r-process happens inside stars if the neutron flux density is so high that the atomic nucleus has no time to decay via beta emission in between neutron captures. The mass number therefore rises by a large amount while the atomic number (i.e., the element) stays the same. Only afterwards, the highly unstable nuclei decay via many β- decays to stable or unstable nuclei of high atomic number.

Famous quotes containing the words capture, high and/or flux:
“This is no rune nor symbol,
what I mean is it is so simple
yet no trick of the pen or brush
could capture that impression;
what I wanted to indicate was
a new phase, a new distinction of colour.”
—Hilda Doolittle (1886–1961)
“There can be no high civility without a deep morality, though it may not always call itself by that name.”
—Ralph Waldo Emerson (1803–1882)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (1906–1975)
