proton capture उदाहरण वाक्य

उदाहरण वाक्य

1. Some speculated mechanisms for their formation include proton capture as well as photodisintegration, although 115 Sn might also be partially produced in the s-process, both directly, and as the daughter of long-lived 115 In.
2. At the same time as B 2 FH, Alastair Cameron independently realized the necessity to add another nucleosynthesis process to neutron capture nucleosynthesis but simply mentioned proton captures without assigning a special name to the process.
3. If the conditions required for this rapid proton capture are only present for a short time ( the timescale of explosive astrophysical events is of the order of seconds ), the waiting points limit or hamper the continuation of the reactions to heavier nuclei.
4. Such proton captures on stable nuclides ( or nearly stable ), however, are not very efficient in producing p-nuclei, especially the heavier ones, because the electric charge increases with each added proton, leading to an increased repulsion of the next proton to be added, according to Coulomb's law.
5. Such nuclei are called p-nuclei, and their origin is not yet well understood : some speculated mechanisms for their formation include proton capture as well as photodisintegration . 140 Ce is the most common isotope of cerium, as it can be produced in both the s-and r-processes, while 142 Ce can only be produced in the r-process.
