Langmuir mechanism of low-frequency stimulated Raman scattering on nanoscale objects

V. B. Oshurko, O. V. Karpova, A. N. Fedorov +4

A simple physical mechanism of stimulated light scattering on nanoscale objects in water suspension similar to Langmuir waves mechanism in plasma is proposed. The proposed mechanis…

High harmonic generation in time-dependent quantum box

S. Z. Rakhmanov, H. Abduvakhidov, O. V. Karpova +1

We consider optical harmonic generation in time-dependent box driven by external time-periodic field. Two types of the external field is considered: Time-periodic optical field and…

Laser excitation of gigahertz vibrations in Cauliflower mosaic viruses suspension

N. V. Tcherniega, S. M. Pershin, A. F. Bunkin +8

The interaction of laser pulses with the Cauliflower mosaic virus (CaMV) in a Tris-HCl pH7.5 buffer is investigated. 20 ns ruby laser pulses are used for excitation. Spectra of the…

Stimulated low-frequency Raman scattering in tobacco mosaic virus suspension

O V Karpova, A D Kudryavtseva, V N Lednev +6

Laser pulses interaction with tobacco mosaic virus (TMV) in Tris-HCl pH7.5 buffer and in water has been investigated. 20 ns ruby laser pulses have been used for excitation. Spectru…

Semiempirical charge distribution of clusters in the ion sputtering of metal

Victor I. Matveev, Olga V. Karpova

We propose the generalization of a known established empirically (Wahl W. and Wucher A. Nucl. Instrum. Meth. B 94, 36(1994)) power law, describing relative mass-spectra of neutral…
