Question

A muonic atom contains a nucleus of charge $Ze$ and a negative muon, ${\mu }^{-}$ , moving about it. The ${\mu }^{-}$ is an elementary charge with $-e$ and a mass that is approximately $200$ times as large as an electron mass. Then

• A. the first Bohr orbit of the muonic atom with Z =1 is ${10}^{-13}m$
• B. the binding energy of a muonic atom with Z =1 is $2720eV$
• C. the wavelength of the first line in the Lyman series for such this atom is $6.5\stackrel{\circ }{A}$
• D. the wavelength of the first line in the Lyman series for such this atom is $5.5\stackrel{\circ }{A}$

Answer 1

Answer: (A), (B), (C)

The correct options are
A the first Bohr orbit of the muonic atom with Z =1 is ${10}^{-13}m$
B the binding energy of a muonic atom with Z =1 is $2720eV$
C the wavelength of the first line in the Lyman series for such this atom is $6.5\stackrel{\circ }{A}$

the first Bohr orbit of the muonic atom with Z =1 is ${10}^{-13}m$

The binding energy of a muonic atom with Z =1 is $2720eV$
The wavelength of the first line in the Lyman series for such this atom is $6.5\stackrel{\circ }{A}$
