摘要: The 738 keV 7/2− isomeric state in43K (Τ=292 ± 5 ns,g=1.266 0.015) was produced in the reaction4He(40Ar,p) using 185 MeV pulsed40Ar beam of VICKSI and a 2–7 bar helium target cell. suitability this for hyperfine studies during recoil gases after implantation into solids investigated via TDPAD technique. deorientation highly stripped43K ions He Xe interpreted with AbragamPound model. When adding up to 15% gas, near-exponential loss alignment partial pressure observed. This effect can be explained by K-hole production Xe-K collision which cross section ofσ=5 · 10−18 cm2 estimated.
