A way of analyzing the energy spectra of backscattered particles is suggested which makes it possible to extract from the measured spectra the dependence of the average relative energy loss of channelled particles on the depth of dechanneling. The results of the energy loss determination of protons channelled in a tungsten crystal are presented.
Резюме. Приводятся результаты учетов редких и малоизученных видов птиц, выполненные в 2011 г. в различных районах Приамурья и Юго-Западного Приохотья. Сообщаются новые сведения о 28 видах птиц, среди которых 26 внесены в Красные книги Хабаровского края, Еврейской автономной и Амурской областей.Summary. Rare and insufficiently studied birds were counted in 2011 in several districts of Priamurje and South-Western Priokhotje. Presented count data include new information on 28 bird species, 26 of which are listed in the Red Books of Khabarovskii Krai, Jewish Autonomous Oblast and Amurskaya Oblast.
Резюме. Впервые приводятся сведения, доказывающие размножение кулика-сороки в Юго-Западном Приохотье на территории Хабаровского края. До настоящего времени вид был известен для данного региона только в качестве редкой пролетной птицы.Summary. Data proving Eurasian Oystercatcher nesting in the south-western Priokhotje region of Khabarovsky Krai are presented for the first time. Hitherto this species was known in the region as a rare migrating bird.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
