"The $3/2$$^-$ ground state of gallium-61, Ga-61, is bound by only $190$ keV relative to the system: Zn-60 + p, where p is a proton. There are excited Ga-61 states at $271$ keV and $1000$ keV"
How do I interpret the first sentence of that statement?
My attempt was to think that, if I were to draw an energy level diagram for this situation, I would put the ground state of Ga-61 at the zero energy, then the two excited states above it at $271$ keV and $1000$ keV. Then on this same diagram, I would put the system: (Zn-60 + p) at $-190$ keV, that is, $190$ keV below the zero energy ground state of Ga-61. Is this the correct way to interpret this situation?
