Lifetimes of bound states in 15O

The lifetime values of 8.2 +- 1.0, > 3000, < 2.5, 16.0 +- 2.5 and 750 +- 200 fs for the first, second, third, fifth and sixth bound states in 15O, at 5183, 5241, 6176, 6859 and 7276 keV, respectively, were determined with the DSA method through the 14N(p,γ)15O reaction. The experimental correction factors of the nuclear and electronic stopping powers were used in the DSA analysis. In the calculations the Monte Carlo method was employed. The transition strengths are discussed in terms of shell-model calculations. (Auth.)
