How long can an electric lamp of 100 W be kept glowing by fusion of 2.0 kg of deuterium? Take the fusion reaction as :

_{1}^{2} H +_{1}^{2} \to_{2}^{3} He + n + 3.27 M e V

Calculate the height of the potential barrier for a head on collision of two deuterons.

From the relation R =

R_{0} A^{\frac{1}{3}}

, where

R_{0}

is a constant and A is the mass number of a nucleus, show that the nuclear matter density is nearly constant (i.e. independent of A).

Text solutionVerified

For a head on collision, distance between centers of two deuterons=

2 \times r a d i u s = r = 2 \times 2 f er mi = 4 \times 1 0^{- 15} m

Charge of each deuteron=

1.6 \times 1 0^{- 19} C

Potential energy=

\frac{e ^{2}}{4 π ϵ _{0} r} = 360 k e V

Potential energy=

2 \times

Kinetic Energy of Deuteron

= 360 k e V

This is the measure of height of Coulomb Barrier Potential.

Thus Kinetic energy of each deuteron=

180 k e V
