It’s deterministic enough to make extremely accurate predictions of the measured results of experiments. Even if there’s plenty of room for debate about whether or not a given particle was here or there when its position can’t be measured.
True enough, the applicability of quantum indeterminism to neurons is a difficult and unclear subject …. but you didn’t say brains are deterministic, you said particles were.
Let me phrase it this way, then. If free will exists, then brains must be at least partially non-deterministic (or, just for completeness, the decision must somehow originate somewhere else). Brains consist of neutrons, electrons, and protons, which must obey the laws of physics.

Of some experiments.

That’s the wrong way round. You are asuming that underlying determinism is the default option, and that quantum indeterminism is a weird minority position, that needs to make its case. But actually, it is quantum determinism
which is fighting the rearguard action, after Bells theorem and the Aspect experiment.

That’s not a complete argument....you need to add the premise that obeying the laws of physics entails determinism.

You’re right, that’s missing. I’m no longer certain that it’s warranted… I don’t know enough about quantum physics to be completely certain one way or the other.
