What are the units for E minimum?

with reference to what?

The units for E minimum can vary depending on the context in which it is being used. Without any specific context, it is difficult to determine the exact units for E minimum.

However, in general, E minimum often refers to the minimum energy of a system or particle. In physics, energy is typically measured in joules (J) or electron volts (eV).

To determine the units for E minimum in a specific context, you would need to refer to the equation or definition that describes E minimum and see what units are involved in that particular case. For example, if E minimum is determined by a gravitational potential energy equation, the units may be in joules (J), whereas if it is calculated using a quantum mechanics equation, the units may be in electron volts (eV).
