电荷为+1的夸克和其他反常氢，已经用伯克利的88英寸回旋加速器作为高能质谱仪，用天然氢和氘作为离子源来寻找。没有观察到夸克，它们与地球上质子的比例被限制在< 2 x 10- 19（高质量）（3到8.2原子质量单位）到10-13（最低质量）（<伪原子质量单位）之间。
Quarks of charge +1 and other anomalous hydrogen have been sought by using the 88-inch cyclotron at Berkeley as a high-energy mass spectrometer, with natural hydrogen and deuterium as the sources of ions. No quarks were observed, and limits were placed on their ratio to protons on the earth that vary from < 2 x 10–19for high masses (3 to 8.2 atomic mass units) to 10–13 for the lowest masses (< ⅓ atomic mass unit).
