ABSTRACT
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 possibility of separating, with the aid of photoemulsion, channels of the reaction [sup 12]C(γ, n³He)2α that involve the formation of [sup 7]Be and [sup 8]Be intermediate nuclei in excited states is studied. The experimental energy distributions of these nuclei are obtained. The...

    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...
