Suppose we have 12 protons and 12 neutrons. We can assemble them to form either a `^24 Mg` nucleus or two `^12 C` nuclei. In which of the two cases more energy will be liberated?

A proton and a neutron are both shot at 100 m//s towards a _(6)^(12)C nucleus. which particle,if either is more likely to be absorbed by the nucleus ?

The compound unstabel nucleus ._(92)^(236)U often decays in accordance with the following reaction ._(92)^(236)U rarr ._(54)^(140)Xe +._(38)^(94)Sr + other particles During the reaction, the uranium nucleus ''fissions'' (splits) into the two smaller nuceli have higher nuclear binding energy per nucleon (although the lighter nuclei have lower total nuclear binding energies, because they contain fewer nucleons). Inside a nucleus, the nucleons (protonsa and neutrons)attract each other with a ''strong nuclear'' force. All neutrons exert approxiamtely the same strong nuclear force on each other. This force holds the nuclear are very close together at intranuclear distances. A proton and a neutron are both shot at 100 m s^(-1) toward a ._6^(12)C nucleus. Which particle, if either, is more likely to be absorbed by the nucleus?

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. Binding energy per nucleon is maximum.

There are 12 different books in a shelf. In how many ways we can select atleast one of them?

A deuterium reaction that occurs in an experimental fusion reactor is in two stage: (A) Two deuterium (._1^2D) nuclei fuse together to form a tritium nucleus, with a proton as a by product written as D(D,p)T . (B) A tritium nucleus fuses with another deuterium nucleus to form a helium ._2^4He nucleus with neutron as a by - product, written as T (D,n) ._2^4He . Compute (a) the energy released in each of the two stages, (b) the energy released in the combined reaction per deutrium. (c ) What percentage of the mass energy of the initial deuterium is released. Given, {:(._1^2D=2.014102 am u),(._1^3 T=3.016049), (._2^4 He =4.002603 am u),(._1^1 H =1.007825 am u),(._0^1 n =1.00665 am u):} .

Assertion (A) : Neutrons have no charge but protons are positively charged, hence net result is repulsion in them in the nucleus of an atom. In the presence of this repulsion the nucleus is highly stable. Reason (R) : The pair of nucleons (neutrons and protons) continuously exchanges the charge through mesons which may either be positively or negatively charged.

Four nuclei of an elements undergo fusion to form a heavier nucles, with release of energy. Which of the two - the parent or the daughter nucleus - would have higher binding energy per nucleon ?

Calculate the energy released when three alpha particles combine to form a _^12 C nucleus. The atomic mass of _^4 He is 4.002603 u .
