When a positron collides with a neutron, a particle referred to as a positronium (H+) is formed. How would the emission spectra of a hydrogen (H) atom and a positronium compare?

A. Identical
B. Positronium would produce more spectral lines than hydrogen.
C. Positronium would produce less spectral lines than hydrogen.
D. Positronium would produce no visible spectral lines.

Answer key's Correct Answer: D
(My answer- A)

I thought it would be
0 e + 1 n = 1 positronium
1***** 0*****1
Thus, positronium has the same electronic configuration as Hydrogen. So it should produce the same spectral lines.
(Sorry for the ****. It keeps on messing with the formatting. I put the ***
s to keep the numbers in place. So the positron has a 0 on top and 1 on bottom; neutron has 1 on top and 0 on bottom)

Can anyone please clarify?

There is no electron, so there can be do emission spectra!
