DC put out a hardcover collection of the Atomic Knights back in 2010 -- it is great silver-age sci-fi, but will cost a pretty penny to procure. If you're looking for single issues, the Atomic Knights appeared mainly in the comics Strange Adventures and Weird War Tales, I think. https://www.amazon.com/Atomic-Knights-John-Broome/dp/1401227481/ref=sr_1_1?crid=10IDFYYC1ZGL3&dib=eyJ2IjoiMSJ9.KR3kMAwR9tNk-WwrL92LQeK_M3XZpQqjtJSArMugcSLEWl7tGaHqBjMdlQvwP3-yq9bw7feTArpFPsL2xhWs4OeQLfoYEA2jWoke8Ffj9z-jLrzH5Zi0qVcpuy3BcgA-sr5klhdHaWY_MOEli6SoY2PkVkGL3gxwIKgGzoRT_8wqRYZoER_x45b56WrzuWqStgTT1i0ze1O7BnwE0mZoG77D_78jAI9Dbi6dg4Zz1qc.bX_oY6pO9AImjSkZ71plRvNR1EbMm6gZj55Lc1Zwvyk&dib_tag=se&keywords=atomic+knights&qid=1782149438&sprefix=atomic+knights%2Caps%2C221&sr=8-1
