On the formation and decay of the $pHe^{+}$ atomcule
Up to now it has been observed that a fraction of about 3% of the p's stopped in a dense He target survives for a surprisingly long time (tens of microseconds). As suggested by Condo in 1964 the long lifetime of p's in He is explained by the existence of metastable states of the exotic ato...

| description | Up to now it has been observed that a fraction of about 3% of the p's stopped in a dense He target survives for a surprisingly long time (tens of microseconds). As suggested by Condo in 1964 the long lifetime of p's in He is explained by the existence of metastable states of the exotic atom pHe/sup +/. An analysis of data from p's stopped in He targets at 3 bar pressure by the Obelix apparatus at the LEAR decelerator at CERN is presented. We do not observe any significative amount of "prompt" annihilations (few nanoseconds) after the p's capture. (13 refs). |
