NUCLEAR PHYSICS DIVISION

Introduction

Nuclear Physics Division (NPD) came into existence in 1966 right at the beginning of scientific activities at the Institute. The main objectives of the Division are:

  1. To carry out basic research in various disciplines of physics and materials science.

  2. To provide technical assistance to other PAEC projects.

  3. To train manpower in various experimental techniques used in many PAEC projects.

The Division has been working successfully on these aspects and has published research papers in the national and international journals. NPD has also contributed significantly to a number of projects of Pakistan Atomic Energy Commission by providing experienced manpower and microanalytical facilities.
