    Description / Table of Contents: Riassunto Il gran potenziale e l'energia di un gas elettronico bidimensionale non correlato non interagente, soggetto a quantizzazione di Landau in un campo magnetico, sono esaminate qui a basse temperature. La suscettibilità magnetica oscillatoria di De Haas-Van Alphen per il gas libero 2D è calcolata e i risultati presentati qui incorporano gli effetti di spin (tenendo conto che il taglio di spin non può, in generale, eguagliare uguale separazione del livello di Landau) in formule che hanno la stessa struttura analitica per numeri sia pari che dispari dei livelli completi di Landau.
    Abstract: Резюме В зтой работе при низких температурах исследуется потенсиал и знергия невзаимодействующего некоррелированного двумерного злектроннного газа, подчинющегося квантованию Ландау в магнитном поле. Вычисляется осцилляторная магнитная восприимчивость де Гааза-ван Альфена для свободнго двумерного газа. Полученные результаты учитывают спиновые зффекты (допуская, что спиновое расщепление в общем случае может быть не равно интервалу между уровнями Ландау) в формулах, которые имеют ту же аналитическую структуру для четного и нечетного числа заполненных уровней Ландау.
    Notes: Summary The grand potential and energy of a noninteracting uncorrelated two-dimensional electron gas subject to Landau quantization in a magnetic field are examined here at low temperatures. The DeHaas-Van Alphen oscillatory magnetic susceptibility for the free 2D gas is calculated and the results presented here incorporate the effects of spin (by allowing that spin splitting may not, in general, equal Landau level separation) in formulae that have the same analytic structure for both even and odd numbers of filled Landau levels.

    Notes: For the process of one-dimensional diffusion in a medium with random traps and homogeneous scavenging, we derive exact expressions for the ultimate trapping and scavenging probabilities and for the lifetimes associated with the two processes. This is done for free diffusion, where results agree with those previously found for discrete random walk, as well as for diffusion in a linear potential. The asymptotic expansions, for small and large ratio of trap concentration to scavenging rate, are given and compared numerically to the exact integrals.

    Notes: We point out that the Green function for an electron in an infinitely extended electric field is not unique. We describe the mathematical basis underlying this observation and discuss the choice of Green function appropriate for various situations including "matching'' calculations.

    Notes: We consider the irreversible random sequential adsorption of particles taking k sites at a time, on a one-dimensional lattice. We present an exact expansion for the coverage, θ(t,k)=A0(t)+A1(t)k−1+A2(t)k−2+..., for times, 0≤t≤O(k), and at saturation t=∞. The former is new and the latter extends Mackenzie's results [J. Chem. Phys. 37, 723 (1962)]. For these expansions, we note that the coefficients Ai≥1(∞) are not obtained as large-t limits of the Ai≥1(t). Finally, we comment on the Laurent expansions for general O(k)〈t〈∞, which reveal the occurrence of additional kn terms, with n(approximately-greater-than)0.

    Notes: The factors determining arrival time line shapes in ion drift tube devices are discussed. An analysis is presented for the line shape due to diffusive drift and its modification due to various boundary conditions. The modification of the line shape due to ion neutralization by randomly placed impurities within the drift area is considered.
