(a)

To determine

The energy difference between n=1 and n=2 states if the length of the box is 3 fm.

(a)

Expert Solution

Answer to Problem 37E

The energy difference is 68.4 MeV.

Explanation of Solution

Write the expression for the energy of the nth state of a particle confined in a box.

En = n2h28ma2 (I)

Here, En is the energy in the nth state, h is Planck’s constant, m is the mass of the particle and a is the dimension of the box.

Conclusion:

Substitute 2 for n, 6.626 × 10−34 J⋅s for h, 1.67 × 10−27 kg for m and 3 fm for a in equation (I).

E2 = 22(6.626 × 10−34 J⋅s)28(1.67 × 10−27 kg)(3fm)2(1fm)2(10 −15 m)2= 1.46 × 10−11 J(1 eV1.6 × 10−19 J)= 9.12 × 107 eV= 91.2 MeV

Substitute 1 for n, 6.626 × 10−34 J⋅s for h, 1.67 × 10−27 kg for m and 3 fm for a in expression (I).

E1 = 12(6.626 × 10−34 J⋅s)28(1.67 × 10−27 kg)(3fm)2(1fm)2(10 −15 m)2= 3.65 × 10−12 J(1 eV1.6 × 10−19 J)= 2.28 × 107 eV= 22.8 MeV

Evaluate the difference between E2 and E1.

E2 − E1 = (91.2 − 22.8) MeV= 68.4 MeV

Thus, the energy difference is 68.4 MeV.
