Quantum tunnelling effects revealed in collisions of antiprotonic helium with hydrogenic molecules at low temperatures

Quenching of individual metastable states of antiprotonic helium (pHe /sup +/) in collisions with H/sub 2/ and D/sub 2/ in gas phase was studied using a laser-resonance method at CERN's antiproton decelerator. The temperature dependence of the quenching cross- sections of the pHe/sup +/ states...
