Before you risk your laptop or your morals, consider these legal channels where you can get the book for cheap or free.
While the full PDF is rarely available on Google Books, it is the best legal starting point. Search the exact title on books.google.com. You can often preview 30-50 pages, which covers the table of contents and the first chapter.
According to cybersecurity firms, textbook PDFs are a top vector for malware. Files named Nuclear_Physics_DC_Tayal.pdf.exe or links requiring "password extraction" software are usually trojans.
Why students love it: The solved numerical problems at the end of each chapter. For competitive exams like IIT JAM, JEST, or TIFR, Tayal’s problems are gold.
It is important to note that Nuclear Physics by D.C. Tayal is a copyrighted work published by Himalaya Publishing House. Distributing or downloading free PDFs of this book from unauthorized "warez" or torrent sites constitutes piracy.
Piracy hurts authors and publishers, potentially leading to textbooks going out of print. As students and future scientists, respecting intellectual property is part of academic integrity.
