Drip line — may refer to: Neutron drip line Proton drip line Tree drip line, the area defined by the outermost circumference of a tree canopy where water drips from and onto the ground Drip irrigation line, where the tubes and hoses are laid See also Drip… … Wikipedia
Nuclear drip line — In nuclear physics, the boundaries for nuclear particle stability are conceptualized as drip lines. The nuclear landscape is understood by plotting boxes, each of which represents a unique nuclear species, on a graph with the number of neutrons… … Wikipedia
Neutron drip line — The neutron drip line is a concept in particle and nuclear physics. An unstable atomic nucleus beyond the neutron drip line will leak free neutrons. In other words, the neutron drip line is the line on the Z, N plane (see table of nuclides) where … Wikipedia
Proton emission — (also known as proton radioactivity) is a type of radioactive decay in which a proton is ejected from a nucleus. The decay of a proton rich nucleus A populates excited states of a daughter nucleus B by β+ emission or electron capture (EC). Those… … Wikipedia
P-nuclei — (p stands for proton rich) are certain proton rich, naturally occurring isotopes of some elements between selenium and mercury which cannot be produced in either s or r process. Contents 1 Definition 2 Origin of the p nuclei … Wikipedia
Atomic nucleus — A figurative depiction of the helium 4 atom with the electron cloud in shades of gray. In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom … Wikipedia
Table of nuclides — A chart of nuclides (cut into three parts for better presentation). A table of nuclides or chart of nuclides is a two dimensional graph in which one axis represents the number of neutrons and the other represents the number of protons in an… … Wikipedia
Halo nucleus — In nuclear physics, an atomic nucleus is called a halo nucleus or is said to have a nuclear halo if its radius is appreciably larger than that predicted by the liquid drop model, wherein the nucleus is assumed to be a sphere of constant density.… … Wikipedia
P-process — The term p process (p is for proton) is used in two ways in the scientific literature concerning the astrophysical origin of the elements (nucleosynthesis). Originally it referred to a proton capture process which is the source of certain,… … Wikipedia
CNO cycle — Overview of the CNO I Cycle. The CNO cycle (for carbon–nitrogen–oxygen) is one of two sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain. Unlike the proton–proton chain reaction, the CNO… … Wikipedia
