On the photofragmentation of SF: Experimental evidence for a predissociation channel
We report on the first observation of the photofragmentation dynamics of
SF. With the aid of state-of-the-art ab initio calculations on the
low-lying excited cationic states of SF performed by Lee et al. [J. Chem.
Phys. 125, 104304 (2006)], a predissociation channel of SF is evidenced
by means of resonance-enhanced multilphoton ionization spectroscopy. This work
represents a second experimental investigation on the low-lying excited
cationic states of SF. [The first one is the He I photoelectron spectrum
of SF reported by de Leeuw et al. three decades ago, see Chem. Phys. 34,
287 (1978).]Comment: 7 pages, 3 figures, submitted to JCP as a Not
Non-integrable stable approximation by Stein's method
We develop Stein's method for -stable approximation with
, continuing the recent line of research by Xu \cite{lihu} and
Chen, Nourdin and Xu \cite{C-N-X} in the case The main
results include an intrinsic upper bound for the error of the approximation in
a variant of Wasserstein distance that involves the characterizing differential
operators for stable distributions, and an application to the generalized
central limit theorem. Due to the lack of first moment for the approximating
sequence in the latter result, we appeal to an additional truncation procedure
and investigate fine regularity properties of the solution to Stein's equation
