Bound states in straight quantum waveguides with combined boundary condition
Dittrich, Jaroslav; Kříž, Jan
2002 - Czech
Discrete spectrum of the Hamiltonian describing quantum particle in a straight planar strip with Dirichlet and Neumann boundary condition on the different parts of boundary is studied. Vyšetříme diskrétní spektrum hamiltoniánu popisujícího kvantovou částici v rovném povinném pásu. Neprostupnost stěnyvlnovodu je modelována Dirichletovou a Neumannovou okrajovou podmínkou na různých částech hranice. Ukážeme příklady vlnovodů s vázaným stavem pod prahem esenciálního spectra i bez diskrétního spectra.

Weak decays of 10Be.LAMBDA. and 10B.LAMBDA. hypernuclei: what they tell us?
Majling, Lubomír; Batusov, Yu.; Lukstins, J.; Parfenov, A.; Chren, D.; Sopko, B.
2002 - Czech
Hypernuclei not only bring a new flavor - strangeness to nuclear physics, they provide also a background to extension of nucleon - nucleon interaction into baryon - baryon one. They are a convenient laboratory to study the four baryon.LAMBDA.N -> NN weak interaction and associated effective weak Hamiltonian. We have proposed to use the unique feature of the .sup.9./sup.Be nucleus: after removing a neutron from its ground state several groups of ŕ-particles appear from different excited states of a residual .sup.8./sup.Be. Uvádíme fyzikální motivaci připravovaného experimentu na Nukletronu SÚJV v Dubně - měření bezmezonového rozpadu hyperjader 10Be.LAMBDA. a 10B.LAMBDA.
