Lifetime measurements of first excited states inC16,18

Direct Lifetime Measurements of the Excited States in (72)Ni.

The lifetimes of the first excited 2^{+} and 4^{+} states in ^{72}Ni were measured at the National Superconducting Cyclotron Laboratory with the recoil-distance Doppler-shift method, a model-independent probe to obtain the reduced transition probability. Excited states in ^{72}Ni were populated by the one-proton knockout reaction of an intermediate energy ^{73}Cu beam. γ-ray-recoil coincidences...

First Measurements of the b Lifetime+

This paper reviews the first measurements of the B lifetime, the theoretical and experimental climate in which they were made, and their considerable impact on knowledge of the CKM matrix and B phenomenology.

Unusual behavior in the first excited state lifetime of catechol

Lifetime, Λ-doubling and hyperfine structure measurements in the A 2Π excited states of ZnH, ZnD, CdH and CdD

2014 The hydride (or deuteride) is obtained in the ground state by radiofrequency discharge in a mixture of H2 (or D2) and metal vapor at a total pressure of about 10-2 torr. A selective excitation of the A 203A03/2,1/2 rotational levels is obtained by a pulsed dye laser. Lifetimes are obtained by sampling the fluorescent decay : 03C4 ~ 70 ns. Electric radiofrequency resonances between the ~-do...
