| الوصف: | The cascade of muonic boron and the two-photon decay 2S{r_arrow}1S have been investigated. The x-ray measurement with Ge and Si(Li) detectors was performed at low target gas pressures of pure B{sub 2}H{sub 6} and admixtures with He. The 2S population of {mu}B is found to be {epsilon}{sub 2S}=3.1(2){percent} . Cascade calculations indicate that more than half of the 2S states are populated with an empty electron shell. Two-photon decays have been observed in mixtures of B{sub 2}H{sub 6} in He at partial diborane pressures of 67Pa and below. The measured fraction of metastable 2S states per {mu}B atom is 0.58(16){percent} in an admixture of 1{percent} B{sub 2}H{sub 6} in He at 6.7kPa and is interpreted in terms of pressure dependent quenching. {copyright} {ital 1997} {ital The American Physical Society} |
