Direct measurement of the proton magnetic moment.

چکیده
The proton magnetic moment in nuclear magnetons is measured to be μ(p)/μ(N) ≡ g/2 = 2.792 846 ± 0.000 007, a 2.5 parts per million uncertainty. The direct determination, using a single proton in a Penning trap, demonstrates the first method that should work as well with an antiproton (p) as with a proton (p). This opens the way to measuring the p magnetic moment (whose uncertainty has essentially not been reduced for 20 years) at least 10(3) times more precisely.

Designing an approprate solenoid and magnetic field for the HZDR laser-driven beamline
Nowadays, due to the high costs and large dimensions of the conventional proton accelerators, other optimal methods for producing the proton beam have been studied. Using of Laser-driven proton accelerators is one of the important and new methods. In laser-driven ion acceleration, a highly ultra-intense laser pulse interacts with solid density targets and will create a plasma media that will ac...
متن کاملObservation of spin flips with a single trapped proton.
Radio-frequency induced spin transitions of one individual proton are observed. The spin quantum jumps are detected via the continuous Stern-Gerlach effect, which is used in an experiment with a single proton stored in a cryogenic Penning trap. This is an important milestone towards a direct high-precision measurement of the magnetic moment of the proton and a new test of the matter-antimatter ...
متن کاملMeasurement of the (anti)proton g-factor - Status of the experiment
The measurement and comparison of the magnetic moment (or g-factor) of the proton and antiproton provide a stringent experimental test of the CPT-theorem in the baryonic sector [1]. We set up an experiment for the first selfcontained and direct high-precision measurement of the gfactor of a single isolated proton stored in a Penning trap [2]. In previous experiments the g-factor was determined ...
متن کاملAntiproton magnetic moment determined from the HFS of pHe
We report a determination of the antiproton magnetic moment, measured in a three-body system, independent of previous experiments. We present results from a systematic study of the hyperfine (HF) structure of antiprotonic helium where we have achieved a precision more than a factor of 10 better than our first measurement. A comparison between the experimental results and three-body quantum elec...
متن کاملMeasurement of the X Magnetic Moment Using the X = ne v and X = - n ~ Decay Modes
We have used the spin-precession technique to measure the X magnetic moment (p, x). A X beam with a polarization of 22'/0 was produced by a 400-GeV proton beam striking a Cu target at nominal production angles of +3 mrad. We simultaneously recorded 21000 X ne v decays and 650000 X n~ decays at X beam momenta of 253 and 308 GeV/c. We find p, x = —1.166 +0.014 +0.010 nuclear magnetons, where the ...
