Time-resolved x-ray absorption spectroscopy has been used to observe the transient species generated by one-photon detachment of an electron from aqueous bromide. The K-edge spectrum of the short-lived Br(0) atom exhibits a resonant 1s-4p transition that is absent for the Br(-) precursor. The strong 1s-4p resonance suggests that there is very little charge transfer from the solvent to the open-...

The existence of n-particle n-hole deformed yrare bands in the N=28 isotones is explored using full pf -shell diagonalizations and the Lanczos Strength Function method. We find different 2p-2h and 4p-4h collective bands that, when allowed to mix, more often disappear. Only the 2p-2h yrare band in Cr and the 4p-4h yrare band in Ni survive, and only in this latter case, due to the reduced density...

lower is a group of transitions involving ls 4p simultaneous with ligand-to-metal shakedown. About 18.7 eV below the main peak is a weak (65 times weaker) quadrupole-allowed transition corresponding to 1s 3d (i.e., ls 3d ls'3d' ). These results are in agreement with typical assignments of x-ray absorption spectra of Cu(tt) systems except that the middle transition is usually assigned as 1s 4s, ...

Wolf-Hirschhorn syndrome (WHS) is a chromosome disorder (4p-syndrome) which is characterized by craniofacial features and epileptic seizures. Here, we report a case of WHS with West syndrome, in whom the seizures were refractory to several antiepileptic drugs but were responsive to the addition of lamotrigine. The patient had epileptic spasms at age seven months. The interictal electroencephalo...

A method for the calculation of x-ray photoelectron spectra (XPS) based on the use of the normalized elimination of the small component (NESC) formalism combined with the restricted active space state interaction (RASSI) approach with atomic mean field integrals (AMFI) is developed. Benchmark calculations carried out for the 4f XPS of U show that the NESC/RASSI/AMFI method is capable of reprodu...

We classify all {δvμ+1, δvμ;N, p3}-minihypers, δ ≤ 2p − 4p, p = p0 ≥ 11, h ≥ 1, for a prime number p0 ≥ 7, with excess e ≤ p − 4p when μ = 1 and with excess e ≤ p + p when μ > 1. For N ≥ 4, p non-square, such a minihyper is a sum of μdimensional spaces PG(μ, p) and of at most one (possibly projected) subgeometry PG(3μ + 2, p); except for one special case when μ = 1. When p is a square, also (po...

A {0,±1}-matrix S is called a Siamese twin design sharing the entries of I, if S = I +K − L, where I,K,L are non-zero {0, 1}-matrices and both I + K and I + L are incidence matrices of symmetric designs with the same parameters. Let p and 2p−1 be prime powers and p ≡ 3 (mod 4). We describe a construction of a Siamese twin Menon design with parameters (4p, 2p − p, p − p), yielding a Siamese twin...

The present paper treats application of the EQPET (Electronic Quasi-Particle Expansion Theory) model for TSC (Tetrahedral Symmetric Condensate) of H/D mixed systems for Pd host metal. Production ratios of He/He for multi-body fusion reactions in H/D mixed TSC systems are calculated as a function of H/D mixing rate. The model is further extended to treat direct nuclear interactions between host-...
