What is meant by deuterium mix ion species - D+,D2+, D3+, etc. in a deuterium plasma?

A deuterium has no excited state and only one proton, neutron and electron each. So, these seems like the charge state of an proton. But, how can the charge state be more than +1. Or, is this the...

Do you think the experimental value of 0.8758fm from before 2010 perfectly matches the Standard Model prediction for the regular proton radius so far?

Although there are new attempts using the exotic atoms of hydrogen and deuterium since 2010 to measure the regular radius of the proton, is it legitimate to consider that the value 0.8758fm is...
