Muons are a fascinating probe to study nuclear properties. Muonic atoms can easily be formed by stopping negative muons inside a material. The muon is subsequently captured by the nucleus and, due to its much higher mass compared to the electron, orbits the nucleus at very small distances. During this atomic capture process the muon emits characteristic X-rays during its cascade down to the ground state. The energies of these X-rays reveal the muonic energy level scheme, from which properties like the nuclear charge radius or its quadrupole moment can be extracted. While almost all stable elements have been examined using muons, probing highly radioactive atoms has so far not been possible. The muX experiment has developed a technique based on transfer reaction inside a high pressure hydrogen/deuterium gas cell to examine targets available only in microgram quantities.
Comment on "Nuclear structure corrections in muonic deuterium"
最近的一封信[1]研究了μ D原子中氘核极化率的影响。了解这个原子的重要性已经提高,因为它可能会对质子半径之谜有所启发。在这里,我们确认,澄清,并强调的结果[1]的意义,第三泽马赫矩的影响被部分的氘核极化率效应抵消。1. K. Pachucki,Phys. Rev. Lett. 106、193007(2011)
