Measurement of the stepwise excitation constants for the e3? and b3? states of CO in a plasma
Autor: N. P. Penkin, V. I. Blashkov, Yu. Z. Ionikh
Publikováno v: Soviet Physics Journal. 27:791-794
Measurements have been made on the rate constants for the stepwise excitation SE of the e3σ and b3σ states of CO from the a3π metastable state of CO. The measurements were made in the positive column of a discharge in a mixture of He + 0.1% CO by

Publikováno v: Astrophysics. 17:437-441
The multichannel method of delayed coincidences in intersecting atomic and electron beams has been used to measure the lifetimes of 33 excited levels of Nd I and 11 levels of Nd II. Values obtained for the Nd I excited level lifetimes are used to con

Outstanding Center for the Development of Scientific Thought (On the 150th Anniversary of Leningrad University)
Autor: N. P. Penkin
Publikováno v: Soviet Education. 11:36-44
February 20, 1969, marks the 150th year since the founding of the A. A. Zhdanov State University, Order of Lenin, one of the oldest centers of science and learning in our country. Originally, the university consisted of three faculties: Philosophy, H

Determination of the temperature dependence of the rate constant representing quenching of metastable iodine atoms by iodine molecules
Autor: V. A. Kartazaev, Yu A Tolmachev, N. P. Penkin
Publikováno v: Soviet Journal of Quantum Electronics. 7:608-610
The rate constant of quenching of the 5p5 2P1/2 level of atomic iodine by I2 molecules was determined in the gas temperature range 293–1000°K. The experimental results fitted the approximate formula k(T) = 8x10–11exp(–4.4×10–3T) cm3/sec.
