The (n,n[sup ′]γ) reaction has been used to study the properties of low-lying excited states of [sup 207]Pb. Gamma-ray excitation functions, angular distributions, and coincidences have been measured, and the lifetimes of many excited levels were determined with the Doppler-shift attenuation method (DSAM). A sextuplet of states near 3.2 MeV is interpreted as resulting from particle-vibration coupling of the f[sub 5/2] neutron hole, the first excited state of [sup 207]Pb, with the octupole phonon of the [sup 208]Pb core. © 2000 American Institute of Physics.

    The coupled processes of intermolecular photoinduced forward electron transfer and geminate recombination between the (hole) donor (Rhodamine 3B) and (hole) acceptors (N,N-dimethylaniline) are studied in three molecular liquids: acetonitrile, butyronitrile, and benzonitrile.

    We have investigated the doubly excited 2 s2 p 3 P o and 2 s3 p 1 P o resonance states of H- embedded in a model plasma environment. Plasma effects are taken care of by using a screened Coulomb (Yukawa-type) potential. Correlated wave functions are used to represent the correlation effect...

    The population of excited states of the hydrogen atom in an afterglow plasma produced by a pulsed discharge in helium (40 Torr) with a small admixture of hydrogen ([H2] ≈ 1012 cm–3) has been studied spectroscopically. The contribution from electron–ion recombination Γrec3...

    A new mechanism of prebreakdown generation of electron–hole pairs is considered. It includes a cascade of interband multiphoton transitions as well as Auger-type processes involving two or three photons. A combination of these processes leads to the multiphoton avalanche effect. The...

    This talk discusses a general argument that QCD in the large Nc limit must have a Hagedorn spectrum-that is, a spectrum where the number of hadrons grows exponentially with the mass of the hadron. The derivation of the Hagedorn spectrum is based on a study of correlation functions of composite...

    The superheavy hydrogen isotopes4H and5H have been investigated in the stopped pion absorption on9Be. Three states of4H were proposed in the reaction channel9Be( p{ - }, dt)X. Four states of5H were proposed in the reaction channels9Be(p{ - }, pt)Xand9Be(p{ - }, dt)X. The excited states of5H can...
