It is shown that these angles decrease from 36° to 10° when pulsars move to the “death line”. Such values correspond to kinematic ages from 1 to 10 millions of years. It is detected also that for these ages radio luminosities of pulsars decrease. This means that radio pulsars fade out when their age increases.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257553707584">Проведены вычисления углов \(\beta \) между магнитным моментом и осью вращения в радиопульсарах, находящихся на разных расстояниях от “линии смерти”. Показано, что при приближении к “линии смерти” \(\beta \) уменьшается от 36° до 10°. Эти значения соответствуют пульсарам с кинематическим возрастом от 1 до 10 млн. лет. Показано также, что при этом уменьшается их светимость, что свидетельствует о постепенном затухании радиопульсара при увеличении его возраста.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neutron stars</kwd><kwd>radio pulsars</kwd><kwd>angles between axes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейтронные звезды</kwd><kwd>радиопульсары</kwd><kwd>наклоны осей</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>L.
