proton capture मीनिंग इन हिंदी

Magnesium can be burned by proton capture reactions.
These nuclides are then converted into p-nuclei through sequences of beta decays after the rapid proton captures ceased.
Then the proton capture sequences continue.
Recent scientific literature therefore suggests to use the term p-process only for the actual proton capture process, as it is customary with other nucleosynthesis processes in astrophysics.
Under conditions encountered in astrophysical environments it is difficult to obtain p-nuclei through proton captures because the Coulomb barrier of a nucleus increases with increasing Proton number.
It is possible to cover the region of the lightest nuclei up to 56 Ni within a second because both proton captures and beta decays are fast.
Typically proton capture in the rp-process will compete with ( ?, p ) reactions, as most environments with a high flux of hydrogen are also rich in helium.
A possible alternative would be to have a very large number of protons available to increase the effective number of proton captures per second without having to raise the temperature too much.
Here, a series of ( p, ? ) reactions proceeds until either the beta decay of a nucleus is faster than a further proton capture, or the proton drip line is reached.
In 1988, however, sales began to pick up and by early 1997, the various models of the Proton captured more that 80 per cent of the market of cars below the 1600cc engine capacity.
