Abstract

By combining angular correlation results of the positron annihilation quanta with lifetime results it is found that a weak but long-lived (599\ifmmode\pm\else\textpm\fi{}10 ps) lifetime component can be correlated with the para-positronium peak in angular correlation measurements when taking into account both pickoff annihilation and conversion of positronium. Conversion has not been considered in earlier works.
