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:
“Writing prejudicial, off-putting reviews is a precise exercise in applied black magic. The reviewer can draw free- floating disagreeable associations to a book by implying that the book is completely unimportant without saying exactly why, and carefully avoiding any clear images that could capture the reader’s full attention.”
—William Burroughs (b. 1914)
“I affect no contempt for the high eminence he [Senator Stephen Douglas] has reached. So reached, that the oppressed of my species, might have shared with me in the elevation, I would rather stand on that eminence, than wear the richest crown that ever pressed a monarch’s brow.”
—Abraham Lincoln (1809–1865)
“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)
