Atomic and Nuclear Physics
Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change. Nuclear physics is the field of physics that studies the constituents and interactions of atomic nuclei.

RUTHERFORD SCATTERING APPARATUS
This experiment demonstrates the Rutherford's scattering experiment. A cylindrical plastic chamber houses a Po-210 alpha particle source at one end, and 8.6cm diameter circle of alpha particle-sensitive film at the other. The film develops in 2.5 molar NaOH. Beam angle of particle source is 2.5 degrees, with deflecting angle of 20 degrees in both positive and negative side. Film is exposed to approximately for 7 days. The set-up also requires a vacuum pump to evacuate the chamber, stereo microscope for viewing film, beaker and heater for film processing.

VERNIER RADIATION MONITOR VRM-BTD
The Vernier Radiation Monitor consists of a Geiger-Mueller tube mounted in a small, rugged, plastic case. It requires no battery, getting power from the data-collection interface. A thin window protected by a metal screen allows alpha radiation to be detected, along with beta and gamma. It can be used to explore radiation statistics, measure the rate of nuclear decay, and monitor radon progeny.
Sensor Requirements
The Vernier Radiation Monitor requires a compatible interface and software to collect data. Interface and software sold separately.
X-RAY APPARATUS
The experiment chamber is contained in a closed, radiation-proof housing with a transparent synthetic-glass shield. The high vacuum X-Ray tube with the directly heated tungsten cathode and copper anode is positioned in a borosilicate glass chamber with a thin walled, concave ray emission window. A lead glass hood with a collimator causes X-rays to emerge in parallel with the experiment plane and provides a shield against scattered radiation. The horizontal counter tube goniometer consists of a central sample holder and the swiveling arm. In the form of a slight ray, this arms serves as a mount for the GM Tube, ionization chamber as well as experimental devices in slide format or on a 5cm X 5cm base plate. This swiveling arm can be rotated manually independently of the sample holder or at a fixed mutual angle with the ratio of 2:1, for instant, for experiments involving Bragg's refection. The devices equipped with angle and mm scale, position marking for experimental devices, as well as radiation proof bushings for cables and houses.
