# IIT JEE Mains and Advanced video lectures for Nuclear Physics (Mass defect and q value of reaction). The notes and videos on Nuclear Physics have been prepared meticulously by highly qualified and experienced teachers in the field of IIT Preparation having vast experience teaching in Kota. Since, IIT is a problem solving based approach exam, the students not going to coaching centers don't

According to the book: "Nuclear and particle physics" by Williams, $Q_\alpha$ is the measure of available energy to permit an alpha decay. It is defined as: $$ Q_\alpha = M(Z,A)-M(Z-2,A-4)-M(2,4)$$ (in natural units) where M is the nuclear mass, defined as: $M(Z,A) = …

Alpha Decay – Q-value In nuclear and particle physics the energetics of nuclear reactions is determined by the Q-value of that reaction. The Q-value of the reaction is defined as the difference between the sum of the rest masses of the initial reactants and the sum of the masses of the final products , in energy units (usually in MeV). • q-value is calculated by using following equation; • rqd = degree of jointing • jn = number of joint sets • jr=joint roughness number • ja=joint alteration number • jw=joint water reduction factor • srf=stress reduction factor
Q value of a nuclear reaction is diffence between the final and initial kinetic energy. Q = Tf -Ti. the importance of the Q-c alue can be understood from following two statements . 1)If Q>0 then the reaction proceeds even if Ti =0 (exoergic reaction) 2)If Q <0 the reaction proceeds only if Ti >= |Q| (endoergic reaction)

In nuclear and particle physics the energetics of nuclear reactions is determined by the Q-value of that reaction. The Q-value of the reaction is defined as the difference between the sum of the masses of the initial reactants and the sum of the masses of the final products , in energy units (usually in MeV). Q Values The Qvalue of a nuclear reaction is the diﬀerence between the sum of the masses of the initial reactants and the sum of the masses of the ﬁnal products, in energy units (usually in MeV). This is also the corresponding diﬀerence of the binding energies of the nuclei (not per nucleon), since nucleon number is conserved in a reaction.

The measurement of the total energy or Q value released in a radioactive decay or involved in a nuclear reaction is of interest for interpreting the nuclear transition between mother and daughter This energy is released in the form of gamma radiation. Fusion reactions are said to be exothermic when the amount of energy released (known as the Q value) in each reaction is greater than zero \((Q > 0)\). An important example of nuclear fusion in nature is the production of energy in the Sun. According to the book: "Nuclear and particle physics" by Williams, $Q_\alpha$ is the measure of available energy to permit an alpha decay.
