a The secondary beam was produced by fragmentation of a 92Mo beam on a primary Be target and purified using the A1900 separator. The beam reacted with a second Be target in front of the GRETINA array. The reaction products were identified using the S800 spectrograph. b Principle of the lifetime measurement using the TRIPLEX plunger. The excited reaction products can experience γ-decay between the target and a Ta degrader foil, at high velocity (v/c=0.365 for 86Mo), or after the degrader, at a lower velocity (v/c=0.324 for 86Mo), producing two peaks in the Doppler corrected γ-ray spectrum. The observation of the ratio between the statistics in the slow (purple) and fast (yellow) components provides information on the lifetime of the excited state.
