7/%OH cholesterol in a cholesterol rich growth medium (5-10 pg/ml) extended the lag period and slowed down the growth rate of Mycoplasma cupricolum cells. In a cholesterol poor medium (0.5 fig/ml) inadequate to support growth, 7j%OH cholesterol exerts a synergistic effect on growth. The 78-OH cholesterol was incorporated unchanged from the growth medium and could be recovered exclusively in the membrane fraction. The incorporation of the 78-OH cholesterol has no effect on the total phospholipid content but the DPG to PG ratio was markedly decreased. Exchange studies with lipid vesicles revealed that whereas most of the cholesterol underwent exchange, only about 20% of the 7/?-OH cholesterol was exchanged.

Absolute total cross sections for deuteron photodisintegration between 7 and 19 MeV

The total deuteron photodisintegration cross section has been determined in an alternative way, based on the absolute measurement of the 90' cross section and, to a lesser extent, the 0' and 180' cross sections. The accuracy of the deduced total cross sections amounts to 3%, including systematic errors. The agreement of our data with the results from recent theoretical calculations is very good.PACS number(s): 25.20. -x, 27.10.+h For a number of reasons, the study of the characteristics of the deuteron photodisintegration process has continuously attracted a lot of attention, from both the experimental and the theoretical side. More specifically, this reaction has been considered as a fundamental testing ground for the details of the nucleon-nucleon interaction. At present, the correspondence between the experimental photodisintegration data and the results from conventional theoretical approaches (including mesonexchange currents, isobaric configurations, and relativistic spin-orbit terms) seems to have reached a satisfying level. In particular, the magnitude of the total photoabsorption cross section in the low-energy region (here arbitrarily defined as the interval between the reaction threshold and, say, 25 MeV) can be extremely well described by theory. This agreement is accentuated by the high accuracy (3 -5% total uncertainty, i.e. , the sum of statistical and systematic errors) of the results from the total absorption measurements [1,2]. Such accuracy is necessary as the predictions from the various theoretical calculations are in accordance with each other within the 2%%uo level.Results from direct H(y, p) measurements [3] have a somewhat larger uncertainty (about 7%), while the data deduced from the neutron-proton radiative capture experiments [4 -9] generally show a 5 -10% total error. A balanced review of all data in the relevant energy range has been given in Refs. [2] and [8], while the general status of the theoretical as well as the experimental situation for the deuteron photodisintegration is extensively described in a recent review by Arenhovel and Sanzone [10]. However, there also exists an indirect way to determine the total photodisintegration cross section with good accuracy. This is based on an adequate knowledge of the Now at Master Foods, +d sin Ocos0+e sin 0, with 0 the c.m. proton emission angle; the so-called "Partovi coefficients" a up to e contain the information concerning the e.m. multipolarity of the involved transition(s). Consequently, one obtains (0') = a +c, do o (2) (180')=a -c, do (3) (90') =a +b +e, der (4) while the total absorption photodisintegration cross section O. T reads cr r = 4m (a + , ' b + , ', e) . --Alternately, the latter can be written as (5) cr r = 4ir -a + -( 90') -e 1 2 do, 2 3The knowledge of o. T now solely depends on the magnitude of the various terms entering the above expression; in principle, these should all be taken from experiment.In previous papers [12], we have described our results for the forward, backward, and 90' deuteron photodisintegra...

Measurement of the capture reaction H(n, d)γ at 25.6 MeV

Abstract: The neutron-proton capture reaction has been measured at E, = 25.6 MeV.From the data the total and the differential cross section at 0" were determined. The results are compared with photodisintegration data and theoretical calculations and found to be in agreement with both.
