Match the nuclear processes given in Column I with the appropriate option(s) in Column II:

If $$\lambda$$_{Cu} is the wavelength of K_{$$\alpha$$} X-ray line of copper (atomic number 29) and $$\lambda$$_{Mo} is the wavelength of the K_{$$\alpha$$} X-ray line of molybdenum (atomic number 42), then the ratio $$\lambda$$_{Cu}/$$\lambda$$_{Mo} is close to

The mass of a nucleus $$_Z^AX$$ is less than the sum of the masses of (A-Z) number of neutrons and Z number of protons in the nucleus. The energy equivalent to the corresponding mass difference is known as the binding energy of the nucleus. A heavy nucleus of mass M can break into two light nuclei of masses m_{1} and m_{2} only if (m_{1} + m_{2}) < M. Also two light nuclei of masses m_{3} and m_{4} can undergo complete fusion and form a heavy nucleus of mass M' only if (m_{3} + m_{4}) > M'. The masses of some neutral atoms are given in the table below :

$$_1^1H$$ | 1.007825 u | $$_1^2H$$ | 2.014102 u |
---|---|---|---|

$$_3^6Li$$ | 6.015123 u | $$_3^7Li$$ | 7.016004 u |

$$_{64}^{152}Gd$$ | 151.919803 u | $$_{82}^{206}Pb$$ | 205.974455 u |

$$_1^3H$$ | 3.016050 u | $$_2^4He$$ | 4.002603 u |

$$_{30}^{70}Zn$$ | 69.925325 u | $$_{34}^{82}Se$$ | 81.916709 u |

$$_{83}^{209}Bi$$ | 208.980388 u | $$_{84}^{210}Po$$ | 209.982876 u |
