摘要：

Laser-induced fluorescence of a fast beam of Mn+ ions has yielded lifetimes of the z P-7o1,2,3 levels with a precision of about 2.4% and of the z P-7o2,3,4 levels with a precision of about 1.4%. The ratios ofthose results to the lifetimes obtained from Kurucz's calculated of values are consistent with the trend found previously for low-lying levels in Fe II. Analysis of solar photospheric data (in combination with the Kurucz of values renormalized by the new lifetime results) yields a solar manganese abundance that is given by log Mn = 5.55 +/- 0.09, in close agreement with the meteoritic value.
