Nuclei Test - 1...

If $$M_{0}$$ is the mass of an oxygen isotope $$_{8}O^{17}$$ , Mp and $$M_{N}$$ are the masses of a proton and a neutron respectively, the nuclear binding energy of the isotope is

A radioactive nucleus (initial mass number A and atomic number Z) emits $$3$$ $$\alpha$$-particles and $$2$$ positrons. The ratio of number of neutrons to that of protons in the final nucleus will be

Assume that a neutron breaks into a proton and an electron. The energy released during this process is
(Mass of neutron $$=1.6725\times 10^{-27}  kg$$, Mass of proton $$=1.6725\times 10^{-27}  kg$$ ,Mass of electron $$=9\times 10^{-31}  kg$$)

The energy spectrum of $$\beta- particles$$ [number $$N(E)$$ as a function of  of $$\beta-energy\ E$$] emitted from a radioactive source is

If the binding energy per nucleon in $$_{7}^{}\textrm{3}Li$$ and He nuclei are $$5.60 MeV$$ and $$7.06 MeV$$ respectively, then in the reaction  $$p+_{3}^{}\textrm{7}Li\rightarrow _{2}^{}\textrm{4}$$ He, binding energy is

The binding energy per nucleon of deuteron $$(_{1}\mathrm{H}^{2})$$ and helium nucleus $$(_{2} \mathrm{He}^{4} )$$ is $$1.1 $$$$\mathrm{M}\mathrm{e}\mathrm{V}$$ and $$7$$$$\mathrm{M}\mathrm{e}\mathrm{V}$$ respectively. If two deuteron nuclei reacts to form a single helium nucleus, then the energy released is

The binding energy per nucleon for the parent nucleus is $$\mathrm{E}_{1}$$ and that for the daughter nuclei is $$\mathrm{E}_{2}$$.Then

In gamma ray emission from a nucleus

The above is a plot of binding energy per nucleon $$\mathrm{E}_{\mathrm{b}}$$, against the nuclear mass $$\mathrm{M};\mathrm{A},\ \mathrm{B},\ \mathrm{C},\ \mathrm{D},\ \mathrm{E},\ \mathrm{F}$$ correspond to different nuclei. Consider four reactions :
(i) $$\mathrm{A}+\mathrm{B}\rightarrow \mathrm{C}+\epsilon$$
(ii) $$\mathrm{C}\rightarrow \mathrm{A}+\mathrm{B}+\epsilon$$
(iii) $$\mathrm{D}+\mathrm{E}\rightarrow \mathrm{F}+\epsilon$$
(iv) $$\mathrm{F}\rightarrow \mathrm{D}+\mathrm{E}+\epsilon$$
where $$\epsilon$$ is the energy released ? In which reaction is $$\epsilon$$ positive ? 

The correct statement is
