摘要:

在光子能量为277- 357 MeV,θ_cm = 20 °- 120 °范围内,对d(极化γ,极化p)n中的反冲质子的诱导和转移极化进行了高精度的测量。测量的动机是长期存在的介子-重子模型计算和更高能量的数据之间的差异。在这个实验的低能量下,理论仍然无法重现数据,这表明计算中缺少了一些东西和/或使用的核子-核子势的准确性存在问题。

英文摘要:

High precision measurements of induced and transferred recoil proton polarization in d(polarized gamma, polarized p})n have been performed for photon energies of 277--357 MeV and theta_cm = 20 degrees -- 120 degrees. The measurements were motivated by a longstanding discrepancy between meson-baryon model calculations and data at higher energies. At the low energies of this experiment, theory continues to fail to reproduce the data, indicating that either something is missing in the calculations and/or there is a problem with the accuracy of the nucleon-nucleon potential being used.
