抄録

The C<SUB>2</SUB> d<SUP>3</SUP>Π<SUB>g</SUB>-a<SUP>3</SUP>Π<SUB>u</SUB> (<I>v</I>′−<I>v</I>″) Swan band emission spectrum induced by the laser ablation of graphite in the superfluid helium around 1.5 K, was observed. Only the vibrational progression of Δ<I>v</I>=<I>v</I>′−<I>v</I>″, where Δ<I>v</I> less than 0 are observed, indicating fast (τ<100 ns) vibrational relaxation in superfluid helium. This result also indicates a unique characteristic of superfluid helium as a circumstance of chemical processes.
