Metastable 2S muonic-hydrogen atoms undergo collisional 2S quenching, with rates which depend strongly on whether the µp kinetic energy is above or below the 2S -P energy threshold. Above threshold, collisional 2S -P excitation followed by fast radiative 2P -S deexcitation is allowed. The corresponding short-lived...

Laser spectroscopy of the 2S-Lamb shift in muonic hydrogen (μ−p) is being performed at the Paul Scherrer Institute, Switzerland, to determine the root-mean-square (rms) proton charge radius with 10−3 precision. A multistage laser system has been developed which provides 0.2 mJ pulse energy tunable at 6 μm wavelength. An excimer pumped dye laser is used to drive a...
