15. A star initially has 1040 deuterons. It produces energy via the 3 4 processes, H² +₁H² →→ ₁H³ + p and, H² + ₁H³ → ₂Heª + n. 1 the If the average power radiated by the star is 10¹6 W, deuteron supply of the star is exhausted in a time of the order of (a) 106 S (c) 10 ¹² s (b) 108 s (d) 10¹6 s The mass of the nuclei are as follows M(H²) = 2.014 amu; M(n) = 1.008 amu; M(p) = 1.007 amu; M(He* )= 4.001 amu. 4

Calculate the threshold energy for the following reactings: (i) n+Th²³2 → Th²³1 + 2n (ii)n+Th232 → Th²33 + y

6 (II) Naturally occurring uranium is a mixture of two iso- topes 235U and 238U. (They have the same position in the periodic table but have different masses.) To produce "en- riched uranium," with a greater fraction of 235U that is required by nuclear reactors, the compound UF, is first formed and the gas allowed to diffuse through porous mate-
