  • The Idaho researchers observed that reversing the intrinsic angular momentum, or “spin,” of thorium-229’s outermost neutron seemed to take 10,000 times less energy than a typical nuclear excitation. The neutron’s altered spin slightly changes both the electromagnetic and strong forces, but those changes happen to cancel each other out almost exactly. Consequently, the excited nuclear state barely differs from the ground state. Lots of nuclei have similar spin transitions, but only in thorium-229 is this cancellation so nearly perfect.

    Basically, thorium-229 can be excited by conventional lasers instead of gamma rays. Instead of millions of electron volts, it takes less than 10, which means it’s more reliable and more precise.






  • Yep, the only reason Motorola stopped producing them is because Motorola sold that business out to Zebra. Hell, zebra still supports the 4000, the 6300 is quite literally just a newer version.

    Same deal with the MC33 scanner. My warehouse has an assortment of Zebra and Moto branded devices and Zebra handles servicing them all. Embedded industrial PCs don’t change much.
