Quantum tunneling of a complex systems: effects of finite size and intrinsic structure

A simple model is considered to study the effects of finite size and internal structure in the tunneling of bound two-body systems through a potential barrier. It is demonstrated that these effects are able to increase the tunneling probability. Applications may include nuclear fusion,hydrogen atom and Cooper pair tunneling.Comment: 9 page

Bremsstrahlung radiation by a tunneling particle

We study the bremsstrahlung radiation of a tunneling charged particle in a time-dependent picture. In particular, we treat the case of bremsstrahlung during alpha-decay, which has been suggested as a promissing tool to investigate the problem of tunneling times. We show deviations of the numerical results from the semiclassical estimates. A standard assumption of a preformed particle inside the well leads to sharp high-frequency lines in the bremsstrahlung emission. These lines correspond to "quantum beats" of the internal part of the wavefunction during tunneling arising from the interference of the neighboring resonances in the well.Comment: 4 pages, 4 figure

МАТЕМАТИЧЕСКАЯ МОДЕЛЬ СЛАБОСВЯЗАННОГО ИНЕРЦИАЛЬНО-СПУТНИКОВОГО НАВИГАЦИОННОГО КОМПЛЕКСА ВОЗДУШНОГО ПРИМЕНЕНИЯ

The paper considers a mathematical model of loosely-coupled inertial-satellite navigation complex which has been developed in the class of linear discrete stochastic models. A specific feature of the considered algorithms for integration of navigation data is the possibility to use parametrical optimum evaluation of the linear Kalman filters constructed on the basis of equations. Strap-down inertial reference system of routes and vertical,  strap-down inertial navigation system, geomagnetic orientation system, system of air signals, satellite radio-navigation system have been used as sources of initial navigation data. The considered navigation complex allows to obtain the whole spectrum of flight navigation parameters which are necessary for flight operation of a tactical unmanned aircraft.Рассмотрена математическая модель слабосвязанного интегрированного инерциально-спутникового навигационного комплекса, разработанная в классе линейных дискретных стохастических моделей. Отличительной особенностью рассмотренных алгоритмов интегрирования навигационной информации является использование параметрического оптимального оценивания, построенного на базе уравнений линейного фильтра Калмана. В качестве источников первичной навигационной информации использованы бесплатформенная инерциальная система курса и вертикали, бесплатформенная инерциальная навигационная система, система геомагнитного ориентирования, система воздушных сигналов, спутниковая радионавигационная система. Рассматриваемый навигационный комплекс позволяет получить весь спектр пилотажно-навигационных параметров, необходимых для выполнения полета тактического беспилотного летательного аппарата в автоматическом режиме

New 32^{32}Cl(p,γ\gamma)33^{33}Ar reaction rate for astrophysical rp-process calculations

The $^{32}$Cl(p,$\gamma$)$^{33}$Ar reaction rate is of potential importance in the rp-process powering type I X-ray bursts. Recently Clement et al. \cite{CBB04} presented new data on excitation energies for low lying proton unbound states in $^{33}$Ar obtained with a new method developed at the National Superconducting Cyclotron Laboratory. We use their data, together with a direct capture model and a USD shell model calculation to derive a new reaction rate for use in astrophysical model calculations. In particular, we take into account capture on the first excited state in $^{32}$Cl, and also present a realistic estimate of the remaining uncertainties. We find that the $^{32}$Cl(p,$\gamma$)$^{33}$Ar reaction rate is dominated entirely by capture on the first excited state in $^{32}$Cl over the whole temperature range relevant in X-ray bursts. In the temperature range from 0.2 to 1 GK the rate is up to a factor of 70 larger than the previously recommended rate based on shell model calculations only. The uncertainty is now reduced from up to a factor of 1000 to a factor of 3 at 0.3-0.7 GK and a factor of 6 at 1.5 GK.Comment: To be published in Phys. Rev.
