Bestimmung der Lebensdauer des 3P-Zustands von ionisiertem Helium aus der Linienbreite von Hochfrequenzübergängen
Tóm tắt
The dependence of the half-widths of 3S
1/2(m=−1/2)↔3P
1/2(m=−1/2)-transition signals in ionized helium on rf power has been measured. By linear extrapolation of the squared half-widths towards zero power, a value of τ3P
=(0.324±0.011) nsec for the lifetime of the 3P-state has been deduced (theoretical value 0.329 nsec).
